What is the mean translational kinetic energy of the gas molecules?

The expression for gas pressure developed from kinetic theory relates pressure. The more familiar form expresses the average molecular kinetic energy, energy used here is limited to the translational kinetic energy of the molecules.

∙ 9y agoYou haven't described where the gas is or what's actually going on. The mean translational KE of all of the gas molecules in a jarful of gas sitting on the shelf must be zero. Otherwise the jar would float off the shelf. Of course, if the gas is flowing from one place to another through a pipe, then then its molecules have some non-zero mean KE, and also some positive non-zero momentum in the direction down the pipe toward the low-pressure end.

Why nitrogen diffuses faster in high temperature?
Higher temperatures mean more heat energy which translates into more kinetic energy of the molecules of nitrogen gas. This greater kinetic energy allows the molecules to diffuse faster than at a lower temperature and lower kinetic energy.
The average kinetic energy of the molecules in an object is what law of thermodynamics?
The root mean square of the velocity.
What happens to kinetic energy of the particles of a substance as the substance changes from a liquid to a gas?
The faster the molecules of a substance are moving, the warmer that substance is, because temperature is really a measurement of the average kinetic energy of the molecules in a substance or object. For a substance to evaporate, or change from a liquid to a gas, it has to become warmer. That means that the kinetic energy of the molecules increases.
How does an airplane flying have kinetic energy?
It has kinetic energy because it is moving. Just because it is in the air doesn't mean that it can't have kinetic energy.
Does kinetic energy mean in motion?
yes it does mean in motion

What is the measure of the average kinetic energy of molecules in the air?
mean free path and RMS velocity .............................................................GHo$t
Is ideal gas one whose particles take up space?
An ideal gas is a theoritical gas consisting of randomly moving particles.The kinetic theory of ideal gases makes 5 main assumptions:The size of molecules is negligible compared with the mean intermolecular distance (i.e. they are widely spaced molecules).Molecules move with different speeds and in random directions.Standard laws of motion apply.Collisions between molecules are elastic. Translational kinetic energy is not converted into other forms of energy.There are no attractive intermolecular forces between molecules except during collision.
What does it mean if an object has kinetic energy?
an object has no kinetic energy if it is not moving
What does it mean if an object has no kinetic energy?
an object has no kinetic energy if it is not moving
What does kinetic energy mean in science?
Kinetic energy is energy of movement. If an object moves it has kinetic energy. For instance, when you walk chemical energy in your food is converted to kinetic energy in your muscles.
Is kinetic is motion energy?
Kinetic energy is energy related to movement or motion, if that's what you mean.

When potential energy turns into kinetic do the air molecules expand?
Molecules of air are mainly nitrogen and oxygen, N2 and O2. The '2' subscript means each molecule contains two atoms. The molecules themselves do not change with changes in energy, pressure, temperature etc. I'm not sure what you mean by potential energy turning into kinetic energy. I can visualise one route, where you have air pressurised in a container, then you release the pressure and the air rushes out, gaining kinetic energy. In this case the molecules of air will soon collide with the air that they are going into and be slowed down until mixed and at the same pressure and temperature. The density of the air will be lower than it was in the pressurised container. This means not so many molecules in a unit volume, so their mean distance apart will be greater. If that is what you mean by 'expand' then I agree, but the molecules themselves are not altered.
