Consider two systems: A and B$.$ System A contains $3$ kg of liquid$-$vapor water

mixture at quality of $0\mathrm{.}2.$ System B contains $3$ kg of liquid$-$vapor water mixture at quality of $0\mathrm{.}7.$ The

temperatures of both mixtures A and B are $150$C$.$ Which system has more internal energy: system A

or system B or do they have the same internal energy? Briefly explain.

a$)$ After cylinder reaches thermal equilibrium with the reservoir, what is the final state of the water

in the cylinder? Is it a compressed liquid, saturated liquid, mixture, saturated vapor, or superheated

vapor? Briefly explain.

b$)$ Is the heat during this process taking energy from the water to the reservoir, or the other way around?

Briefly explain.

c$)$ Is this a reversible process or an irreversible process? Briefly explain.
