Explain work done during a thermodynamic process.

As area under P-V diagram represent work done by gas in a thermodynamic process, area under temperature (T) entropy (S) graph represents heat supplied to the thermodynamic system. Consider the following graph

Mechanical Workdone During Various Thermodynamic Processes

Define adiabatic process. Derive an expression for work done during adiabatic process.

Can the work done during a cyclic process be zero?

A : In nature all thermodynamic processes are irreversible. R : During a thermodynamic process it is not possible to eliminate dissipative effects.

What is a cyclic process ? Prove that the net work done during a cyclic process is numerically equal to the area of the loop representing the cycle.
