Consider a system consisting of an ideal gas confined within a container, one wall of which is a movable piston. Energy can be added to the gas in the form of heat by applying a flame to the outside of the container. Conversely, energy can also be removed from the gas in the form of heat by immersing the container in ice water. Energy can be added to the system in the form of work by pushing the

The movable piston

Explanation:

Work is said to be done when a distance is been covered by a force . In this case kinetic energy will be change by an equal amount into work done.

Pushing the piston with a known mass of (m) and an accelarating rate from rest of ( a)   to cover a known distance of (d).The idea of work done is been achieved and can be mathematically represented by:

heat the gas and measure the pressure
