In thermodynamics, isothermal and adiabatic processes are two fundamental types of thermodynamic processes that describe how a system’s temperature and energy change under specific conditions.
Isothermal Process:
-In an isothermal process, the temperature of the system remains constant throughout the entire process.
-This means that as the system undergoes changes, the temperature doesn’t increase or decrease; it stays the same.
-Heat is exchanged with the surroundings to maintain this constant temperature.
-An isothermal process is like a system in thermal equilibrium, where heat flows to or from the surroundings to keep the temperature steady.
Adiabatic Process:
-An adiabatic process is one where there is no heat transfer between the system and its surroundings.
-During an adiabatic process, the change in the system’s internal energy is solely due to work done on or by the system.
-It’s as if the system is insulated and doesn’t allow any heat to enter or leave.
-Adiabatic processes are often associated with fast changes, and the system’s energy change is mainly through mechanical work, not heat.
