A system performs work $\Delta W$ when an amount of heat $\Delta Q$ is added to the system. The corresponding change in the internal energy is $\Delta U . \mathrm{A}$ unique function of initial and final states irrespective of the mode of change is (a) $\Delta W$ (b) $\overline{\Delta Q}$ (c) $\Delta W$ and $\Delta Q$ (d) $\Delta U$
Internal energy and entropy are state functions a. internal energy (U) is a state function and $\Delta \mathrm{U}$ is independent of path. b. In a cyclic process: $\Delta \mathrm{S}=0$ but $\Delta \mathrm{U} \neq 0$ c. $\mathrm{Cv}$ values of $\mathrm{H}_{2}$ and He are equal at all temperatures d. $\mathrm{q}$ and $\mathrm{w}$ are path dependent
Which of the physical quantities, $Q, W$, or $\Delta E$, is zero in an isothermal process?
