audience, purpose, thesis. Possibly the two most important things a writer must consider are audience and purpose. ... In this sense, audience and purpose work in two directions: A writer's audience will influence his purpose, while his purpose will influence which audience the writer chooses to address.

Density and Volume are inversely proportional to each other. ... When density increases, volume decreases. When volume increases, density decreases.

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.

Factors causing chemical shifts Important factors influencing chemical shift are electron density, electronegativity of neighboring groups and anisotropic induced magnetic field effects. Electron density shields a nucleus from the external field.

The shape, weight, volume, density, porosity and water displacement also factor in to its floating ability. A steel boat, for example, will float while a steel bar will sink because of the density compared to the amount of water and also because of the form/shape the object is in.

In other words, the size or amount of a material/substance does not affect its density. 3. Does temperature affect density?

The size, mass, and arrangement of atoms affect the density of a substance.

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.

The mass difference between two objects causes heat transfer. The density difference between two objects causes heat transfer. The temperature difference between two systems causes heat transfer. The pressure difference between two objects causes heat transfer.

The atmosphere and Earth's interior are layered by density. Gravity pulls more strongly on denser materials so denser materials are at the center of things. Earth's core, at its center, is denser than its crust. The lowest layer of the atmosphere is denser than the upper layer.

Temperature Affects Density When the same amount of water is heated or cooled, its density changes. ... When comparing two samples of water with the same salinity, or mass, the water sample with the higher temperature will have a greater volume, and it will therefore be less dense.

Density: Why It Matters Pressure, temperature and humidity all affect air density. And you can think of air density as the mass of air molecules in a given volume.

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.

The density of water can also be affected by temperature.

...

The warmer the water, the more space it takes up, and the lower its density.

When comparing two samples of water with the same salinity, or mass, the water sample with the higher temperature will have a greater volume, and it will therefore be less dense..

Factors Affecting The Speed of SoundThe Density of Medium: Sound requires a medium to travel. The density of the medium is among the factors which affect the speed of sound. ... The Temperature of The Medium: Higher the temperature, the higher is the speed of sound in the medium.

Key Concepts: There are two main factors that make ocean water more or less dense: temperature and salinity. Cold, salty water is denser than warm, fresher water and will sink below the less dense layer. Density is defined as the measure of a material's mass (e.g. grams) divided by its volume (e.g. milliliters).

In air: Wind can increase or decrease the speed, and can even push sound waves sideways. Air density affects it. Temperature, pressure, humidity and gas mixture can each affect the density. In liquid: The speed of sound is affected by density and viscosity.

-Any setting that only increases the shading quality, resolution, or anti-aliasing quality of objects typically only impacts the GPU. ... Mostly, everything graphics-related is a GPU thing, and CPU performance is pretty independent on settings. Things like "population density" would be the exception.

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.

When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.

SummaryThe factors that affect buoyancy are… the density of the fluid. the volume of the fluid displaced. the local acceleration due to gravity.The buoyant force is not affected by… the mass of the immersed object. the density of the immersed object.

The important product characteristics that affect logistics are dollar value, density, susceptibility to damage and special handling requirements..

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.

Two forces act on an object when it enters water: a downward force called gravity and an upward force called buoyancy.

...

If an object is more compact, or denser, than water, it will sink in water.

If the density of an object is less than the density of water, the object will float in water..

One of the three most important settings in photography is Shutter Speed, the other two being Aperture and ISO.

Learning anything new. On a physiological level, learning new things is good for your brain. ... Additionally, learning new skills stimulates neurons in the brain, which forms more neural pathways and allows electrical impulses to travel faster across them. The combination of these two things helps you learn better.

VMCG is affected by density altitude. High density altitude - Less Thrust - Easier aircraft control. Thus VMCG reduces at higher density altitudes.

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.

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.
