When outside temperature increases, what happens to propane inside a container?

When the outside temperature increases, the pressure of propane inside a container increases due to the principles of gas laws, specifically Boyle's Law and Gay-Lussac's Law. As the temperature of a gas rises, the kinetic energy of its molecules increases, causing them to move more vigorously and collide with the walls of the container with greater force. This results in an increase in pressure.

In a closed container, if the temperature goes up, the volume of the container remains constant, meaning that the gas cannot expand to reduce pressure, so it has no choice but to exert higher pressure. This relationship between temperature and pressure is crucial for understanding how gases behave under varying conditions, particularly in the context of storing and handling propane safely. Proper knowledge of these principles is essential for anyone working with gas containers to prevent dangerous situations such as explosions or leaks.
