Suppose 5160 J of heat flow from a reservoir at 385 K to a colder reservoir. If the total entropy change of the universe is +206 J/K, what is the temperature of the cold reservoir? Note: Because the reservoirs are assumed to be very large, their temperatures do not change during this process.

Suppose that there are two very large reservoirs of water, one at a temperature of 95.0 °C, and one at a temperature of 11.0 ℃. These reservoirs are brought into thermal contact long enough for 36330 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...

(a) During each cycle, a Carnot engine absorbs 772 J as heat from a high-temperature reservoir at 388 K, with the low-temperature reservoir at 287 K. How much work is done per cycle? (b) The engine is then made to work in reverse to function as a Carnot refrigerator between those same two reservoirs. During each cycle, how much work is required to remove 1206 J as heat from the low-temperature reservoir? () Numbel 200.9590 UnitsT j UnitsT j (b)...
