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...
