These factors are: the number of protons in the nucleus (called the nuclear charge). the number of energy levels holding electrons and the number of electrons in the outer energy level.

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.

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.

Four Factors That Create Ocean Currents

• Wind. Wind is the single biggest factor in the creation of surface currents.
• Water Density. Another major factor in the creation of currents is water density, caused by the amount of salt in a body of water, and its temperature.
• Ocean Bottom Topography.
• Coriolis Effect.

In ionic bonds, charge and distance are the two factors that affect the strength of the bond. The more electrons transferred, the stronger the bond.

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 two main flow factors in sediment transport are the settling rate and the boundary layer shear stress 27.

An organism's phenotype results from two basic factors: the expression of an organism's genetic code, or its genotype, and the influence of environmental factors. Both factors may interact, further affecting phenotype.

Changes in gene expression can be induced by external factors like environment (diet, smoking), internal signals such as stress (hypoxia, nutrient deprivation), inflammation and tissue repair, and even genetic material such as non-coding RNAs.

Internal factors that can affect gene expression are hormones, metabolic products and gender.

PESTLE stands for Political, Economic Socio-Cultural, Technological, Legal and Environmental. Two important macro-environmental factors that may affect an organisation in the airlines industry are Economic and Technological factors. Economic Factors represent the wider economy.

The frictional force between two bodies depends mainly on three factors: (I) the adhesion between body surfaces (ii) roughness of the surface (iii) deformation of bodies.

The main factors that affect density altitude are pressure, temperature, and humidity. By increasing pressure, the aircraft will perform like it normally would at a lower altitude and by decreasing the pressure it would perform like it's at higher altitudes.

There are two direct factors that affect solubility: temperature and pressure. Temperature affects the solubility of both solids and gases, but pressure only affects the solubility of gases.

There are three important factors that contribute to high density altitude:Altitude. The higher the altitude, the less dense the air. ... Temperature. The warmer the air, the less dense it is. ... Humidity. ... 80 oF.90 oF.100 oF.110 oF.120 oF.More items...

Factors Affecting Radiographic Density. Greater radiographic density may be produced by increasing (1) the total number of x-rays that reach the film, (2) the penetrating power of the x-rays, (3) the developing time, or (4) the temperature of the developer.

Solubility is the maximum amount of a substance that will dissolve in a given amount of solvent at a specific temperature. There are two direct factors that affect solubility: temperature and pressure.

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.

Some factors that affect intensity are the distance away from the epicenter, the depth of the earthquake, the population density of the area affected by the earthquake, the local geology of the are, the type of building construction in the area, and the duration of the shaking.

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.

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.

Abiotic factors that influence aquatic biomes include light availability, depth, stratification, temperature, currents, and tides.

Population Growth Rate The two main factors affecting population growth are the birth rate (b) and death rate (d). Population growth may also be affected by people coming into the population from somewhere else (immigration, i) or leaving the population for another area (emigration, e).

Factors that affect urine pH include vomiting, diarrhea, lung disease, hormones, kidney function, and urinary tract infection..

Newton's law also states that the strength of gravity between any two objects depends on two factors: the masses of the objects and the distance between them. Objects with greater mass have a stronger force of gravity between them.

Answer and Explanation: The two factors that affect the boiling point of water are the pressure the water is under and whether or not there are impurities or particles in the...

The strength of the force of friction depends on two factors; the type of surfaces involves and how hard the surfaces push together, What is one way you could reduce the friction between two surfaces? Ball bearing are one way of reducing friction between two surfaces.

1. Explain that there are two factors that affect how much kinetic energy a moving object will have: mass and speed.

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.

The friction force depends on two factors:a) The materials that are in contact. The two materials and the nature of their surfaces. ... b) The force pushing the two surfaces together. Pushing the surfaces together causes the more of the asperities to come together and increases the surface area in contact with each other.

The influence of climate is due to basically two factors: temperature and rainfall. Climate indirectly affects soil formation through its influence on organisms as well. High temperatures and rainfall increase the degree of weathering and therefore the extent of soil development.
