Question

According to the sixth postulate of the kinetic-molecular theory, a group of gas particles will have an average kinetic energy based on what?

Answer 1

Since the molecules of gas are more spread out than the ones in liquid and solid, they have more kinetic energy in the free space between the molecules.

Answer 2

The answer is Temperature.

Explanation: The molecular kinetic theory describes the behavior and properties of gases. In particular, one of the postulates of this theory indicates that the average kinetic energy of the molecules of any gas is proportional to the temperature of the gas. This means the higher the temperature of the gas, the higher the kinetic energy of the particles.

Therefore, the average kinetic energy of gas particles will depend on the temperature.
