When the pressure of a substance is reduced, it's temperature decreases. This phenomenon can be witnessed around mountain ranges, when air currents are forced up the sides of mountains. As the air is forced up in elevation, it cools because it's pressure drops, causing water to condense out of the air and form clouds. This is why mountains can appear to always have stationary clouds at their peaks, even though the actual air is be exchanged constantly.
This same adiabatic cooling is used in Stirling engines as well.

A process of cooling in which no heat is transferred. So how is this possible? Change of pressure. If the pressure of a substance is reduced, that substance will cool adiabatically.

Adiabatic is a process where gas expands or contracts without losing or gaining heat. How it achieves this, I'm not sure. Perhaps with pressure.

Cooling with no heat transfer into or out of the system. Basically it is cooling due to reducing pressure in a gas.

It is when the pressure of a substance is decreased, such as when the substance expands and takes up more space (or volume).
