-gas molecules move at random with no attractive forced between them

-the velocity of gas molecules is proportional to their kelvin temperature

-the amount of space occupied by a gas is much greater than the space occupied by the space occupied by the actual has moleules

-in collisions with the walls of the container or with other molecules, energy is conserved
