A gas takes part in two processes in which it is heated from the same initial state 1 to the same final temperature. The processes are shown on the p-V diagram by the straight lines 1-3 and 1-2. 2 and 3 are the points on the same isothermal curve. `Q_1` and `Q_2` are the heat transfer along the two processes. Then,

Options

A. `Q_(1) = Q_(2)`
B. `Q_(1)ltQ_(2)`
C. `Q_(1)gtQ_(2)`
D. insufficient data

Answer

B

Explanation

Work done in process `1-3` is greater than that in process `1-2`. While change in internal energy is same for both processes
`therefore Q_(2) gtQ_(1)`.
