Question

A closed container of a gas is heated to a high temperature. What do you predict will happen?

• A. The gas particles will repel each other
• B. The gas particles inside the container will move slower and slower
• C. The pressure inside the container will decrease
• D. The pressure inside the container will increase

Answer 1

The correct option is D The pressure inside the container will increase

When temperature increases, gas particles absorb energy and move far apart from each other hence pressure inside the closed container increases.

Hence, option $D$ is correct.
