Handle Propane Tanks Safely: Understanding Pressure Changes

What happens to the pressure inside a propane tank as the temperature increases?

Choose the correct answer:

a) The pressure decreases

b) The pressure remains constant

c) The pressure increases

Answer:

c) The pressure increases

When a propane tank is exposed to higher temperatures, the pressure inside the tank also increases. This is a crucial factor to consider when handling and storing propane tanks.

As the temperature of the tank rises, the molecules of propane inside the tank gain more kinetic energy. The increased kinetic energy results in more frequent and energetic collisions between the molecules and the walls of the tank. These collisions exert greater force on the walls, causing the pressure inside the tank to rise.

It is important to be aware of this pressure increase to prevent the tank from reaching critical levels that could lead to a rupture or explosion. Always store propane tanks in cool, well-ventilated areas away from high temperatures or open flames to ensure safety.
