Explain quasi-static process
The process in the system the variables (PTV) alters very slowly so that the systems remain in thermal and mechanical equilibrium with its surrounding throughout is known as quasi-static process.
A method in which the temperature of the system is kept constant throughout is called isothermal process. (i.e. ΔT = 0)
REST: A body is said to be at rest if it does not alter its position with respect to its surroundings.
