Adiabatic compression of saturated water vapor typically causes its temperature and pressure to increase. During this process, no heat is exchanged with the surroundings, so the internal energy of the vapor increases due to compression.

This rise in internal energy leads to an increase in temperature and pressure. If the compression continues, the vapor may eventually become superheated, meaning its temperature is above the saturation temperature for its pressure.
