Question

Choose the statement below that is correct for gas particles according to KMT.

1. At a given temperature, the KE of a gas is directly related to the molar mass.That is,as the mass of the gas particle increases, its KE increases.
2.At a given temperature, the KE of all gases is the same.KE depends only on Kelvin temperature
3 The KE of a gas particle and its molar mass are unrelated

Answer 1

2.At a given temperature, the KE of all gases is the same.KE depends only on Kelvin temperature

Step-by-step explanation:

The kinetic molecular theory of gases provides a succint expalantion and insight into the behaviour of gases. The assumptions of the theory are stated below:

1. Gases are made up of large number of identical molecules which are moving at different speeds.
2. Spaces occupied by molecules of gases are negligible compared to the volume of the container.
3. Molecules of gases are independent of one another.
4. The molecules collide with themselves and the walls of the container elastically.
5. The temperature of a gas is a measure of only the average kinetic energy of the molecules.
