(17%) Problem 6: You have mw = 4.9 kg of water in an insulated container. You add mı = 0.15 kg of ice at Ty=-19°C to the water and the mix reaches a final, equilibrium temperature of Tp = 11°C. The specific heats of ice and water are q = 2.10x10 J/(kg-ºC) and cw = 4.19x10 J/(kg:°C), respectively, and the latent heat of fusion for water is 4 = 3.34x10J/kg. Calculate the initial temperature of the water, in degrees Celsius....

Problem 2: (10 pts) A 30-kg iron block at initial temperature 200°C and a 40-kg copper block at initial temperature 100°C are dropped into a very large lake at 20°C. Thermal equilibrium is established after a while as a result of heat transfer between the blocks and lake water. Both blocks have constant specific heats, i.e. Ciron = 0.45 kJ/kg. K and Ccopper = 0.386 kJ/kg. K. Hint: The very large lake can be treated as a heat reservoir and...

3) Adding heat at constant volume: You have a 10 L (10 -2 m 3 ) fixed volume container that initially contains 1 kg of water. The water exists in both vapor and liquid phases, and is at an initial temperature of 180 C. Heat is then added until the final temperature of the water in the container is 250 C. This problem involves calculating the amount of heat that is added to achieve this final state. I will roughly...
