State the assumptions made for thermodynamic processes.

उत्तर
Assumptions made for studying various thermodynamic processes:
- The majority of the thermodynamic processes are reversible. That is, they are quasi-static in nature. They are extremely slow and the system undergoes an infinitesimal change at every stage except the adiabatic processes. The system is, therefore, in thermodynamic equilibrium during all the changes.
- The system involved in all the processes is an ideal gas enclosed in a cylinder having a movable, frictionless, and massless piston.
- The ideal gas equation is applicable to the system.
