Vedclass · Answer

(A) For an ideal gas undergoing compression from $2V_0$ to $V_0$:$1$. Reversible Isothermal: $T_f = T_i$. Work is done on the system,but heat is released to maintain constant temperature.$2$. Reversible Adiabatic: $T_f V_f^{\gamma-1} = T_i V_i^{\gamma-1}$. Since $V_f  T_i$.$3$. Irreversible Adiabatic: The work done is $W = -P_{ext} \Delta V$. Since the process is adiabatic $(q=0)$,$\Delta U = W$. The temperature rise is lower than the reversible adiabatic case because the work done is less efficient.Comparing the final temperatures: $T_{rev, adiabatic} > T_{irrev, adiabatic} > T_{isothermal}$.Thus,the final temperature is highest at the end of the second process.

$A$ sample of gas is compressed from an initial volume of $2V_0$ to $V_0$ using three different processes.
First: Using reversible isothermal.
Second: Using reversible adiabatic.
Third: Using irreversible adiabatic under a constant external pressure.
Then
