A 160 g copper bowl contains 180 g of water, both at 22.0°C. A very hot 370 g copper cylinder is dropped into the water, causing the water to boil, with 9.07 g being converted to steam. The final temperature of the system is 100°C. Neglect energy transfers with the environment. (a) How much energy is transferred to the water as heat? (b) How much to the bowl? (c) What is the original temperature of the cylinder? The specific heat...

Suppose that there are two very large reservoirs of water, one at a temperature of 95.0 °C and one at a temperature of 17.0 °C. These reservoirs are brought into thermal contact long enough for 42130 J of heat to flow from the hot water to the cold water. Assume that the reservoirs are large enough so that the temperatures do not change significantly. What is the total change in entropy resulting from this heat exchange between the hot water...
