Gay-Lussac's Law states that the pressure of a gas is directly proportional to its temperature when the volume is held constant. This means that in a rigid container, as pressure increases, the temperature must also increase to maintain this relationship.

When the gas molecules are compressed (leading to increased pressure), they collide with the walls of the container more frequently and with greater energy. This increase in kinetic energy of the gas molecules results in a rise in temperature. Thus, if the pressure in a rigid container rises, it is indicative of an increase in temperature as well. This concept is fundamental in understanding gas behavior in various scientific applications, including hyperbaric medicine, where these principles are crucial for safe and effective therapeutic practices.
