The temperature of a fixed mass of gas is increased. What happens to the average kinetic energy of the molecules of the gas?
It decreases because the molecules collide with each other less often.
It increases because the molecules of the gas move more quickly.
It stays the same because the mass of the gas is fixed.
It stays the same because the molecules themselves are unchanged.
