What does Gay-Lussac's Law describe?

Gay-Lussac's Law specifically addresses the relationship between temperature and pressure in a fixed volume of gas. It states that when the temperature of a gas increases, the pressure also increases, provided that the volume is held constant. This is because increasing the temperature causes gas molecules to move more rapidly, leading to increased collisions with the container walls, which in turn raises the pressure.

This principle is crucial in many applications, especially in aviation and medical settings where gas behavior can significantly affect equipment and patient care. Understanding this law allows flight paramedics to predict how gases will behave under different temperature conditions, ensuring safety and effectiveness when managing respiratory treatments or other scenarios involving pressurized gas systems.
