Vedclass · Answer

(A) For a monoatomic gas,the molar heat capacity at constant pressure is $C_p = \frac{5}{2} R$.The heat supplied at constant pressure is given by $Q = n C_p \Delta T$.Substituting the value of $C_p$,we get $Q = n \left( \frac{5}{2} R \right) \Delta T$,which implies $n R \Delta T = \frac{2}{5} Q$.The work done by the gas at constant pressure is $W = P \Delta V = n R \Delta T$.Therefore,the work done is $W = \frac{2}{5} Q$.

$A$ monoatomic gas is supplied heat $Q$ very slowly keeping pressure constant. The work done by the gas will be
