Q. A gas $\left( \gamma = \frac{5}{3} \right),\ $expands isobarically. The percentage of heat supplied that increases thermal energy and that is involved in doing work for expansion is
A) l$40:60$
B) $60:40$
C) $50:50$
D) $25:30$
Explanation
(b) $\frac{Q_{1}}{Q_{2}} = \frac{C_{V}dT}{p\ dT} = \frac{\frac{3}{2}R}{R} = \frac{3}{2}that\ is\ 60:40.$
