Vedclass · Answer

(B) For an isobaric process, the work done is given by $W = P \Delta V = nR \Delta T = 100 \ J$.For a diatomic gas, the degree of freedom $f = 5$.The molar heat capacity at constant pressure is $C_p = (\frac{f}{2} + 1)R = (\frac{5}{2} + 1)R = \frac{7}{2}R$.The heat supplied to the gas is $Q = nC_p \Delta T = n(\frac{7}{2}R) \Delta T$.Substituting $nR \Delta T = 100 \ J$, we get $Q = \frac{7}{2} 	imes 100 = 350 \ J$.

$A$ diatomic gas $(\gamma = 1.4)$ does $100 \ J$ of work when it is expanded isobarically. Then the heat given to the gas is . . . . . . $J$.
