What happens to saturated gases when heat is removed?

When heat is removed from saturated gases, they condense to a liquid. This process occurs because saturated gases are in a state where both gas and vapor can coexist at a particular temperature and pressure. As heat is removed, the energy of the molecules in the gas decreases, leading to a reduction in their ability to move freely. Consequently, the molecules start to come closer together and transition into a liquid state.

This fundamental concept is crucial in HVAC and refrigeration systems, where the phase change from gas to liquid is often exploited to remove heat from a designated area effectively. Understanding this phase transition is vital for the operation of various components like condensers and evaporators in refrigeration cycles.
