Piston \(B\) is fixed i.e. it is isochoric process.
If same amount of heat \(\Delta Q\) is given to both then
\({(\Delta Q)_{{\rm{isobaric}}}} = {(\Delta Q)_{{\rm{isochoric}}}}\)==> \(\mu \,{C_p}{(\Delta T)_A} = \mu \,{C_v}{(\Delta T)_B}\)
==>\({(\Delta T)_B} = \frac{{{C_p}}}{{{C_v}}}{(\Delta T)_A} = \gamma {(\Delta T)_A} = 1.4 \times 30 = 42\,K.\)
