Q6-10 True or False The p-V work in a reversible process in a closed system is always p V. The p-V work for a reversible process of a closed system can be found from only the initial and final states. The p-V work for a reversible process of a closed system can be found from only the initial and final states if one also knows the equation of state, p(V,T). For every process U system = - U surroundings . For every cyclic process, the final state of the surroundings is the same as the initial state.

Q11-15 True or False For two systems that consist entirely of liquid water at 1 atm. If system A has more internal energy than system B, then T A > T B . The quantities H, U, PV, H, and p V all have the same units. For a constant volume process U = H. H is only defined for a constant pressure process. For an ideal gas at constant pressure dU = C V dT.

Q16-20 True or False C p is a state function. C p is an extensive property. A Thermodynamic process is defined by the initial and final states. Every process that has T=0 is isothermal. q must be zero for an isothermal process.
