When heat Q is supplied to a diatomic gas of rigid molecules, at constant volume its temperature increases by ∆T The heat required to produce the same change in temperature, at a constant pressure is:

Question

Accepted Answer

Correct answer: C. (c) JEE Main 2019 Amount of heat required (Q ) to raise the temperature at constant volume Q=nC_v T … (i )Amount of heat required (Q_1 ) at constant pressure Q_1=nC_p T … ( ii )Dividing equation ( ii ) by (i ), we get ∴ Q_1Q= C_pC_v ⇒Q_1= (Q ) ( 75 ) ( ∵ = C_pC_v= 75)
