Physics - Heat & Thermo Question with Solution | TestHub

A $\to$B isobaric at $P_0$: $V_0\to 2V_0$, $T_0\to 2T_0$.

$$W_{AB}=P_0{V}_0=R{T}_0$$

B $\to$C isochoric: $W=0$, $P_0\to 2P_0$, $T\to 4T_0$.

Total work

$$=R{T}_0$$

(A) true.

$$\Delta U=\frac{3}{2}R(4T_0-T_0)=\frac{9}{2}R{T}_0$$

(B) false.

$$Q=\Delta U+W=\frac{9}{2}R{T}_0+R{T}_0=\frac{11}{2}R{T}_0$$

(C) true, (D) false.
