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.

An isolated system consists of two very large thermal reservoirs, one hot and one cold, with constant temperatures of 373 K and 273 K, respectively. If 1000 J of heat were to flow from the cold reservoir to the hot reservoir spontaneously, (a) what would be the change in entropy of the hot reservoir? (b) of the cold reservoir? (c) What would be the total change in entropy of the isolated system? (d) could the process take place naturally?

Imagine you have a hot reservoir at a temperature of 89.0 °C, and cold reservoir at a temperature of 15.0 °C. Given their vast size, it is reasonable to assume the reservoirs\' temperatures will not change significantly if heat flows into or out of them. These reservoirs are then brought into thermal contact, during which 39210 J of heat flows from the hot reservoir to the cold reservoir. As a result of this heat exchange, what is the total change...
