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.

An ideal gas is made to go from a state A to stale B in the given two different ways (see figure) (i) an isobaric and then an isochoric process and (ii) an isochoric and then an isobaric process. The work done by gas in the two processes are W1 and W2 respectively. Then,
For an isothermal expansion of a perfect gas, the value of `(Delta "P")/"P"` is equal to ____________.
Assertion: Equal volumes of monatomic and polyatomic gases are adiabatically compressed separately to equal compression ratio `("P"_2/"P"_1)`. Then monatomic gas will have greater final volume.
Reason: Among ideal gases, molecules of a monatomic gas have the smallest number of degrees of freedom.
