JEE MAIN - Physics (2022 - 27th June Evening Shift - No. 21)
A diatomic gas ($$\gamma$$ = 1.4) does 400J of work when it is expanded isobarically. The heat given to the gas in the process is __________ J.
Answer
1400
Explanation
W = nR$$\Delta$$T = 400 J
$$\therefore$$ $$\Delta$$Q = nCP$$\Delta$$T
$$ = n \times {7 \over 2}R \times \Delta T = {7 \over 2} \times (400) = 1400$$
