Arigid tank of volume 0.5 m3 is connected to a piston-cylinder assembly by a valve as shown in the diagram below. Both vessels contain pure water. They are immersed in a constant- temperature bath at 200°C and 600 kPa. Consider the tank and the piston-cylinder as- sembly as the system and the constant-temperature bath as the surroundings. Initially the valve is closed, and both units are in equilibrium with the surroundings (the bath). The rigid tank contains saturated water with...

Consider the tank and the piston–cylinder assembly as the system and the constant temperature bath as the surroundings. Initially the valve is closed and both units are in equilibrium with the surroundings (the bath). The rigid tank contains saturated water with a quality of 95% (i.e., 95% of the mass of water is vapor). The piston–cylinder assembly initially has a volume...

A system consists of a sealed copper tank whose mass is 20kg, which contains 5 kg of liquid water, and an electrical register (negligible mass). The system is insulated on its outer surface. Initially, the temperature of the copper is 27˚C and the temperature of the water is 50˚C. The electric resister transfers 100 kJ of energy to the system. Eventually the system comes to equilibrium. a) Sketch the system. Clearly label all components and include arrows indicating work or...

A cylinder made of brass with a mass of 0.80 kg is heated to 850°C, then dropped into 5.00 kg of water at 11°C. What is the total change in entropy (in J/K) of the cylinder-water system, assuming no energy is lost by heat from this system to the surroundings? The specific heat of brass is 380 J/(kg · K), and the specific heat of water is 4,186 J/(kg · K). (Hint: note that dQ = mcdT.)
