Question

1 mol of an ideal gas initially at 400 K & 20.52 atm is expanded to a final state at 300 K & 1 atm. To
achieve the above change a reversible path is constructed that involve an adiabatic expansion in
beginning followed by an isothermal expansion to final state. AE of the system (CV, m= 1.5R) is -?​

Answer 1

Answer:

Explanation:

heat lost is zero therefore change in internal energy is equal. to work done. 2. Incase of isothermal expansion temperature remains constant therefore change in internal energy is also constant
