Vedclass · Answer

(D) Statement $I:$ $\Delta Q > 0$. According to the $1^{	ext{st}}$ law of thermodynamics,$\Delta Q = \Delta U + W$. If heat is added to a system,it is possible for the system to perform work $W$ such that $W > \Delta Q$,which would result in $\Delta U Statement $II:$ Work done by a system is given by $W = \int P \, dV$. If $W > 0$,then $\int P \, dV > 0$. Since pressure $P$ is always positive for a gas,the change in volume $dV$ must be positive,meaning the volume of the system must increase. Thus,Statement $II$ is true.
