Vedclass · Answer

In both cylinders $A$ and $B$ the gases are diatomic $(Y=1.4) .$ Piston $A$ is free to move i.e. it is isobaric process. Piston $\mathrm{B}$ is fixed i.e. it is isochoric process. If same amount of heat $\Delta Q$ is given to both then

$(\Delta Q)_{	ext {isobaric }}=(\Delta Q)_{	ext {isochoric }}$

$\mu C_{p}(\Delta T)_{A}=\mu C_{v}(\Delta T)_{B}$

$(\Delta T)_{B}=\frac{C_{p}}{C_{v}}(\Delta T)_{A}$

$=\gamma(\Delta T)_{A}=1.4 	imes 30=42 \mathrm{K}$
