A gas is kept in a rigid cubical container. If a load of 10 kg is put on the top of the container, does the pressure increase?

No, pressure will not increase.

Explanation


1. Rigid solid is defined as the solids having definite shape and size. A rigid body does not deform under any force or pressure.


2. Pressure of gas inside a container will only change, if the container gets compressed (deform) under the action of force. In our case, the container is rigid cubical container.


3. So, a load of 10kg will not be able to deform the shape and size of container and hence the pressure of the gas will not increase.
