Consider a container divided by a partition into two chambers. The first chamber contains 15kg of water at 350°C, 1.2 MPa. The other chamber contains 19kg of water at 105°C with 60 percent of the mass is in the liquid phase. The partition is now removed and the water in both chambers are allowed to mix until the system reaches a thermal equilibrium of 120°C.
Determine (a) the final pressure in the container
(b) the vapor mass fraction at the final state

A thermally insulated container is divided by a partition into two compartments, the right compartment having a volume 4 times as large as the left compartment. The left compartment contains 2 moles of an ideal gas A at 25 °C and 0.8 atm. The right compartment contains 2 molesof an ideal gas B at 25 °C. The partition is removed and gases are mixed. Calculate the entropy change in the mixing process.

(a) A student drops two metallic objects into a 120 g steel container holding 150 g of water at 25◦C. One object is a 200 g cube of copper that is initially at 85◦C, and the other is a chunk of aluminum that is initially at 5◦C. To the student’s surprise, the water reaches a final temperature of 25◦C, precisely where it started. What is the mass of the aluminum chunk? Specific heats of water, steel, copper, and aluminum are...

Part A A copper pot of mass 2.5 kg contains 5.2 litres of water (i.e. 5.2 kg) at room temperature (200C). An iron block of mass 9.4 kg is dropped into the water and when the system comes into thermal equilibrium, a temperature of 380C is measured. What is the initial temperature of the iron block? Give your answer in oC to three significant figures. Part B Iron has a specific heat that is larger than that of copper. A...
