Increasing the temperature of gas in a container that cannot expand is a way to . decrease the volume of the gas decrease the volume of the gas increase the pressure of the gas increase the pressure of the gas decrease the pressure of the gas decrease the pressure of the gas increase the volume of the gas

Increase the pressure of the gas

Explanation:

According to the Pressure law, for a fixed mass of gas, at a constant volume (V), the pressure (P) is directly proportional to the absolute temperature (T).

From the kinetic molecular theory, gases are composed of particles which are in constant motion, colliding with themselves as well as with the walls of their container.

When the temperature of these gas molecules is increased, the molecules acquire more kinetic energy and the rate of collisions increases. Since the container cannot expand, the increase in pressure is due to the increase in collisions between the molecules of the gas as well as with the walls of their container.
