A gas is contained in a metallic cylinder fitted with a piston. The piston is suddenly moved in to compress the gas and is maintained at this position. As time passes the pressure of the gas in the cylinder:
- Increases.
- Decreases.
- Remains constant.
- Increases or decreases depending on the nature of the gas.
