The pressure increases.
Explanation
This question is related to the behavior of gases under different conditions, which is described by the gas laws. Specifically, we are looking at a scenario where a gas is enclosed in a rigid container and we are asked how the pressure changes if the gas is heated.According to Gay-Lussac's Law (or the pressure-temperature law), for a given mass of gas at constant volume, the pressure of the gas is directly proportional to its absolute temperature (measured in Kelvin). This means that if the temperature of the gas increases, the pressure will also increase, provided the volume of the container does not change and the amount of gas remains the same.In a rigid container, the volume cannot change. Therefore, when the gas inside such a container is heated, the kinetic energy of the gas molecules increases. Since the molecules are moving faster and colliding with the walls of the container more forcefully and frequently, the pressure exerted by the gas on the walls of the container increases.
