Question

A gas is kept in a rigid cubical container. If a load of $15\text{kg}$ is put on the top of the container, then the pressure of the gas will:
[assume temperature remains constant]

• A. increase
• B. decrease
• C. remain constant
• D. first increase then decrease

Answer 1

The correct option is C remain constant

As container is rigid, the load applied will not be transferred to the gas. Thus, its volume will not change.
Therefore, according to Boyle's law, the pressure will also not change.
