Answer:

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

  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.
