Question

As heat is applied to a closed container containing a gas, what will happen to the pressure inside the container?

1) The pressure inside the container will increase
2) The pressure inside the container will decrease
3) The pressure inside the container will remain the same
4) The pressure inside the container will depend on the type of gas

Answer 1

When heat is applied to a closed container containing a gas, the pressure inside the container will increase.

Step-by-step explanation:

The pressure inside the container will increase when heat is applied to a closed container containing a gas. This is because an increase in temperature of a gas in a rigid container increases the pressure. The increased temperature causes the gas molecules to increase in kinetic energy, resulting in more forceful collisions with the walls of the container and an overall increase in pressure.
