Pressure

Explanation:

According to the pressure law, for a fixed mass of gas, under a constant volume, the pressure is directly proportional to the absolute temperature.

As temperature increase, the collision between molecules increases, hence the frequency of effective collision increases. This causes the pressure in the system to increase.
