Joule expansion, also known as free expansion, is a thermodynamic process in which a gas expands into a vacuum without doing any work and without exchanging heat with its surroundings. This process is adiabatic, meaning there is no heat transfer, and since the gas expands into a vacuum, it is not possible for it to perform work on the surroundings. During Joule expansion, the following key points are observed: 1. **Free Expansion**: The gas expands freely into an empty space.
