Vedclass · Answer

(C) For an isobaric process,the work done is given by $W = P \Delta V = n R \Delta T = 100 J$.For a monoatomic gas,the molar heat capacity at constant pressure is $C_P = \frac{5}{2} R$.The heat supplied to the gas is given by $Q = n C_P \Delta T$.Substituting the value of $C_P$,we get $Q = n (\frac{5}{2} R) \Delta T = \frac{5}{2} (n R \Delta T)$.Since $n R \Delta T = 100 J$,we have $Q = \frac{5}{2} 	imes 100 J = 250 J$.

$A$ monoatomic gas does $100 J$ of work when it is expanded isobarically. How much heat is given to the gas in the process (in $J$)?
