adiabatic process

An adiabatic process is one where a system, such as a gas, changes without exchanging heat with its surroundings. Imagine compressing or expanding a gas quickly enough that heat doesn’t have time to transfer in or out. During this process, the gas’s temperature and pressure change solely due to the work done on or by the gas, rather than heat exchange. This concept is important in thermodynamics and is used in engines, refrigerators, and other systems where controlling heat transfer is essential for efficiency and performance.
