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 (integer)
1400
Solution
<p>W = nR$\Delta$T = 400 J</p>
<p>$\therefore$ $\Delta$Q = nC<sub>P</sub>$\Delta$T</p>
<p>$= n \times {7 \over 2}R \times \Delta T = {7 \over 2} \times (400) = 1400$</p>
