Question

Two identical sample of gases are allowed to expand (i) isothermally (ii) adiabatically work done is :

• A. more in the isothermal process
• B. more in the adiabatic process
• C. equivalent in both process
• D. equal in all process

Answer 1

The correct option is A more in the isothermal process

As the graph of isothermal lies above the adiabatic curve in PV diagram.

So, area under isothermal PV curve is more.
Work done will be more in isothermal.
