Video answer: The number density of molecules of a gas depends on their… ## Top best answers to the question «What does a density in a gas depends on»

• Since gases all occupy the same volume on a per mole basis, the density of a particular gas is dependent on its molar mass. A gas with a small molar mass will have a lower density than a gas with a large molar mass. Gas densities are typically reported in g/L. Gas density can be calculated from molar mass and molar volume.

FAQ

Those who are looking for an answer to the question «What does a density in a gas depends on?» often ask the following questions:

### 👉 Electric force depends on what?

Electric Field strength is given by: E = F e/q' (this was discovered experimentally.) • Where q' (C) is the test charge in the field • F e is the Electrical Force exerted of the test charge by the source charge • E is the Electric field strength There is another way to define the Force on one charge by another charge.

### 👉 Does gas have a density?

Gas Density. An important property of any gas is its density… But for gases, the density can vary over a wide range because the molecules are free to move. Air at the surface of the earth has a very different density than air 50 kilometers above the earth.

### 👉 What is electric flux density?

Flux is the integrated electric field over an area, while flux density is the flux per unit area, which is the electric field by definition. The units are the only thing that ends up being different. The one thing that will drive you crazy about physics is that sometimes, things are referred to by many names.

Video answer: The velocity of sound in a gas depends on its pressure and… The density of gases depends on temperature and pressure.

Answer: The density of gases depends upon the temperature. The higher the temperature, the more the molecules are spread out and the lower the density as shown in the graphic on the left. The result is that warm gases rise and cool gases sink. High pressure means high density, cooler, sinking air.

What happens to the density if the temperature and pressure of an ideal gas are doubled. The pressure of an ideal gas is directly proportional to its pressure. This means you take a can of gas, double its temperature, and the pressure doubles. SO you have the same amount of gas in the same volume, so the density is unchanged.

What affects the density of a gas?

The density of gases depends upon the temperature. The higher the temperature, the more the molecules are spread out and the lower the density as shown in the graphic on the left. The result is that warm gases rise and cool gases sink. The same concept helps to explain the weather resulting in high and low pressures.
