Adiabatic cools by decompression.
In thermodynamics, adiabatic processes do not involve heat transfer, while isentropic processes are reversible and adiabatic.
Adiabatic cooling.
Adiabatic cooling happens as air mass expands with increasing elevation (because density of gases decreases farther into the atmosphere). As elevation increases, the air gets cooler because energy is drawn from the surroundings. Less dense air traps less heat resulting in this net cooling called adiabatic cooling. It occurs at an average of 6 degrees Celsius per 1000 meters, but it can vary.
In thermodynamics, adiabatic processes do not involve heat exchange, isothermal processes occur at constant temperature, and isobaric processes happen at constant pressure.
Adiabatic cooling is cooling that occurs without removing any energy from the system. It often occurs when a gas is decompressed. Adiabatic heating and cooling play an important role in weather.

Adiabatic temperature changes
Adiabatic cooling deals with the cooling of parcels of air as they rise, or are forced up, through the atmosphere.
In thermodynamics, adiabatic processes do not involve heat exchange, isothermal processes occur at constant temperature, and isobaric processes happen at constant pressure.
This is usually adiabatic cooling. Adiabatic refers to a process that does not exchange heat with the air around it. Air that is adiabatically cooled is cooled only because the decreasing pressure with height forces it to cool.
The rate at which adiabatic cooling occurs with increasing altitude for wet air (air containing clouds or other visible forms of moisture) is called the wet adiabatic lapse rate, the moist adiabatic lapse rate, or the saturated adiabatic lapse rate.
In adiabatic processes, there is no heat exchange with the surroundings, so the change in enthalpy (H) is equal to the change in internal energy (U). This means that in adiabatic processes, the change in enthalpy is solely determined by the change in internal energy.

Adiabatic processes involve the exchange of heat, mainly in the environment. More information on this can be found in science textbooks and television shows.
