What factors affect the sedimentation rate?
Asked By: briantist
Date created: May 03, 2022
In addition to particle size, density and concentration, and fluid viscosity, other less obvious factors affect the sedimentation rate. These include particle shape and orientation, convection currents in the surrounding fluid, and chemical pretreatment of the feed suspension.2 Feb 2011

How does density affect settling rate?
Asked By: Adriaan Stander
Date created: May 04, 2022
The settling rate of a particle depends on its size, shape, and density as well as on the vis- cosity of the fluid through which it is settling. In general, smaller particles have a larger sur- face area to mass ratio, so their settling rates are slowed more by frictional drag than are larger grains.

Does mass affect size?
Asked By: Daniel W.
Date created: May 12, 2022
Is mass the same as size? No, mass is different than size or volume. This is because the type of atoms or molecules as well as their density helps to determine the mass. For example, a balloon filled with helium will have much less mass than a similar sized item made of solid gold.

Does size affect buoyancy?
Asked By: BlivetWidget
Date created: May 17, 2022
Because the buoyancy of a solid cube of material depends on its density, which does not vary with the size of the object, changing the size of a cube does not affect whether it will sink or float.

Does Weight Affect density?
Asked By: Richie Cotton
Date created: May 16, 2022
Density has the components of mass and volume, while weight is concerned with mass and gravity. ... Division is used to find an object's density by dividing the mass over volume, while weight is the product of mass and gravity (by virtue of multiplication). 3. The units to express density and weight also differ.

How does air density affect temperature?
Asked By: Pan Vi
Date created: May 10, 2022
Air Density and Temperature This is because warmer molecules of air move faster, creating an expansion effect that decreases air density.
Colder air moves slower, collects together, and sinks with higher density.
This is why warm air rises above cold air..

What are the 4 factors that affect population growth?
Asked By: Maxim Veksler
Date created: May 04, 2022
What we might talk about as population size is actually population density, the number of individuals per unit area (or unit volume). Population growth is based on four fundamental factors: birth rate, death rate, immigration, and emigration.

How do density independent factors affect a population?
Asked By: Phuc Tran
Date created: May 08, 2022
Density independent factors, in ecology, refer to any influences on a population's birth or death rates, regardless of the population density. Density independent factors are typically a physical factor of the environment, unrelated to the size of the population in question.

Does the density of wood affect how fast it burns?
Asked By: David Basarab
Date created: May 09, 2022
The wood sample with highest density was maple with a density of 0.769 gm/cm^3 and maple also had the highest combustion rate with an average time of 3 minutes, 5 seconds before it ignited. My data shows that as the density of the wood gets bigger, the time it takes for the wood to ignite also increases.
A few examples of how density applies to everyday life are in ship building, helium balloons, pipe design and the fact that ice floats on water. Density is defined as an object's mass per unit volume. ... Fluids with greater density are harder to push through a pipe than those with lesser density.
A few examples of how density applies to everyday life are in ship building, helium balloons, pipe design and the fact that ice floats on water. They are able to float in the air because helium gas density is lighter than the density of air. ...
Big bones don't mean (much) extra weight “It's not going to be the difference between a healthy body mass index (BMI) and being overweight.” Some people might confuse bone size with bone density, which refers to the concentration of minerals in your bones.
The effect of weight and of weight change on bone mineral density was in general much less in men than in women. Our results suggest that the strong effect of weight on bone mineral density is due to load on weight-bearing bones in both sexes.
Atom Size - As the atom size increases down a column on the periodic table, the acidity increases. ... Inductive Effect - An electronegative atom will withdraw electron density, stabilizing the conjugate base. This increases the acidity of a molecule.
Density or specific gravity (SG) is affected by entrapped air bubbles in the liquid under test. ... Under pressure the air will dissolve better into the liquid and any bubbles that are left undissolved will be compressed to a fraction of their original size.
The density of an object or quantity of matter is its mass divided by its volume. ... In some cases, materials made of atoms with a lower atomic weight have a greater density than those with a higher atomic weight, due to the atoms being more tightly packed.
Density = Mass/Volume, which means that density is how heavy an object is compared to its size – so how closely its molecules are “packed” together. ... It has a higher density. Density = Mass/Volume also means that the larger the volume of an object compared to its mass, the less dense it is.
Temperature Affects Density When the same amount of water is heated or cooled, its density changes. When the water is heated, it expands, increasing in volume. ... The warmer the water, the more space it takes up, and the lower its density.
Density and temperature As the temperature increases, most materials expand or increase their volume. This results in a decrease in density. Likewise, when the temperature goes down, the density usually becomes greater.
Density is a measure of how heavy something is compared to its size. If an object is more dense than water it will sink when placed in water, and if it is less dense than water it will float. Density is a characteristic property of a substance and doesn't depend on the amount of substance.
Population density influences agricultural intensification by reducing farm size, increasing demand for agricultural inputs such as inorganic fertilizer, lowering farm wages, decreasing revenue from crop sales, creating dependency on off-farm income of limited elasticity (up to 400 persons/ km 2 ), lowering crop yield
Pressure and temperature are the two factors that have the greatest affect on density. Mass and volume are the variables we measure to calculate density. Size and shape have no affect on density. Objects that are the same substance always have the same density, regardless of size and shape.
Two things affect density: 1) thermal energy and 2) pressure. A substance can change density by increasing or decreasing thermal energy and/or by increasing or decreasing pressure. Adding pressure causes a substance's particles to squeeze together or become more compact, which increases it's density.
Does size (or amount) affect density? ... However, the density does not change. This is because the mass and volume increase at the same rate/proportion! Even though there is more molasses (mass) in test tube A, the molasses also takes up more space (volume).
How does gravity affect density? The gravity of the body will work to increase its density. ... If we have more mass then we have more gravity, so atoms would be brought closer together until the electromagnetic repulsion equalizes with the gravity.
Density-dependant factors may influence the size of the population by changes in reproduction or survival. ... This in turn led to a decrease in per capita birth rate, a limitation in population growth as a function of population density. Density dependant factors may also affect population mortality and migration.
Vitamin D status is related to bone mineral density and bone turnover. Vitamin D supplementation may decrease bone turnover and increase bone mineral density. Several randomized placebo-controlled trials with vitamin D and calcium showed a significant decrease in fracture incidence.
For any constant mass, perceived heaviness increases with the object's physical density [34,35,40]. Thus an object's density rather than size might be the second component, next to its mass, which is considered in the judgment of heaviness and which biases our perception in terms of the size-weight illusion.
A few examples of how density applies to everyday life are in ship building, helium balloons, pipe design and the fact that ice floats on water. Density is defined as an object's mass per unit volume. ... They are able to float in the air because helium gas density is lighter than the density of air.
Atoms with smaller atomic radius's will have greater electron density, increasing basicity. Atoms with larger atomic radius's will have less electron density, reducing basicity. Key point: LARGER atomic radius means LOWER basicity. SMALLER atomic radius means HIGHER basicity.
Density dependent factors cause variable changes in the population as its density changes. When the population is small, these factors typically favor increased birth rates and lower death rates, allowing the population to expand.
Environmental factors do affect a population's growth rate, however. The interaction of the population's natural growth rate and the environment determines the density of the surviving population. The maximum number of individuals that a given environment can support is called the carrying capacity.
Whether on the ground or in the air, a variety of forces contribute to the motion of a ball. ... When two balls of the same diameter are made of materials of different density and mass, the ball with the greater mass-density will travel farther if projected with the same amount of force, or at the same initial speed.
As population size approaches the carrying capacity of the environment, the intensity of density-dependent factors increases. For example, competition for resources, predation, and rates of infection increase with population density and can eventually limit population size.
Certain cancer treatments can increase the risk for osteoporosis in both men and women. Some chemotherapy agents can decrease your bone density. It's a rare occurrence. Hormone therapies for breast and prostate cancer can affect bone density, as well.
Factors that affect density altitude are temperature, elevation, humidity, dewpoint and pressure. what will result in high density altitude: high humidity, high temperature, low pressure and high elevation from sea level all contribute to high density altitude. As elevation increases, density altitude also increases.
Living in neighbourhoods with high population density may damage health. ... Although the health-enhancing impact of more active transport among those living in more densely populated neighbourhoods compensated part of this effect, overall, higher density remained associated with a higher risk of mortality.
Demographics can include any statistical factors that influence population growth or decline, but several parameters are particularly important: population size, density, age structure, fecundity (birth rates), mortality (death rates), and sex ratio (Dodge 2006). We introduce each of these in turn.
Objects on the Ground Similar to balls in flight, surface friction impedes the movement of balls with low mass-density, such as soccer balls, more than it does those with high mass-density, such as bowling balls. In other words, given equal size in terms of diameter, the ball with the greater mass will roll farther.

After noting the density of each liquid it became clear that the higher the density the greater the surface tension. The experiment showed that water, the liquid with the highest density, has the highest surface tension; while alcohol,the liquid with the lowest density, has the lowest surface tension.
For objects of the same size and shape, the more dense would have a higher terminal velocity. ... So from a velocity where air resistance cancels gravity on a less dense object, a denser object would continue to accelerate downward.
How does gravity affect density? The gravity of the body will work to increase its density. If we think of gravity as a force then to achieve equilibrium something needs to counteract the force of gravity, usually electromagnetic repulsion caused by neighboring electron shells.
Lift and drag depend linearly on the density of the fluid. Halving the density halves the lift, halving the density halves the drag. The fluid density depends on the type of fluid and the depth of the fluid. In the atmosphere, air density decreases as altitude increases.
Density and Volume are inversely proportional to each other. Mass and volume are not the same. Thus, from the above formula, we can say that, For a fixed mass, When density increases, volume decreases.
As temperature increases, the space between water molecules increases—also known as density, which therefore decreases. If the temperature of water decreases its density increases, but only to a point. ... Evaporation increases salinity and density while the addition of freshwater decreases salinity and density.
