The relationship between temperature and gas pressure is described by Gay-Lussac's Law, which states that if the volume of a gas is held constant, the pressure of the gas is directly proportional to its absolute temperature. This means that as the temperature of a gas increases, its kinetic energy also increases, causing gas molecules to move more rapidly and collide with the walls of their container with greater force. This results in an increase in pressure. Conversely, if the temperature decreases, the kinetic energy of the gas molecules decreases, leading to fewer and less forceful collisions with the container walls, and consequently, a drop in pressure.

This understanding is fundamental in fields such as chemistry and physics, where the behavior of gases is studied under various conditions.
