An adiabatic process is a thermodynamic process in which no heat is exchanged between a system and its surroundings. This means that all the energy changes within the system occur due to work done on or by the system, rather than heat transfer. Adiabatic processes are often idealized situations, but they can occur in real-life scenarios, such as in rapidly expanding gases. In an adiabatic process, the temperature of a gas can change even though no heat is added or removed. For example, when a gas expands quickly, it cools down, while compressing a gas can increase its temperature. These principles are important in understanding the behavior of gases in various applications, including engines and refrigeration systems.
