Isothermal Process:
A process in which the temperature of a system remains constant is called an Isothermal process. The change in volume and pressure in isothermal processes are called Isothermal changes.
Adiabatic Process:
A process in which no heat is exchanged between a system and its surroundings is called an adiabatic process. The change in volume, pressure, and temperature in an adiabatic process are called adiabatic changes.
