Compressing a Gas

An ideal gas is kept in a cylinder fitted with a movable piston.

  • The gas is compressed suddenly by moving the piston downwards.
  • Then, the piston is fixed at the final position and the gas is left in compressed state.

How does the pressure change as the time passes after the gas is left compressed?

Assume: The gas is initially at the same temperature as the surroundings and that the container can exchange heat with the surroundings
