Different type of processes

Question

An ideal diatomic gas under goes a thermodynamic process such that the change in its internal energy is $\frac{Q}{3}$ where Q is the heat supplied to the gas during the process. If ‘C’ be the molar specific heat for the process. Then C =

Moderate

A

7.5 R
B

3.5 R
C

5 R
D

1.5 R

Solution

(1)
$\begin{array}{l} Δ U = \frac{Q}{3}, \\ N o w Q = n . C . Δ T a n d Δ U = n . C_{V} . Δ T \\ ∴ n . C_{V} . Δ T = \frac{1}{3} \times n C . Δ T \\ \Rightarrow n . \frac{5 R}{2} . Δ T = \frac{1}{3} . n . C . Δ T \Rightarrow C = \frac{15 R}{2} \end{array}$
