Q. The circuit is operating in steady state (i.e., the capacitor has already been charged to its max charge possible), what is the current of I5 (hint: once a capacitor is charged to its max, how much current will flow in/out of it)?

Q. Water initially at 300 kPa and 250C is contained in a piston-cylinder fitted with stops. The water is allowed to cool at constant pressure until it exists as saturated vapor and the piston rest on the stops. Then the water continues to cool until the pressure is 100 kPa. On the T-v diagrams sketch, with respect to the saturation lines, the process curve passing through both the initial, intermediate and final states of the water. Label T, P and v values for end states on the process curves. Find the overall change in internal energy between the initial and final states per unit mass of water.
