Two identical long, thin, solid cylinders are used to conduct heat from a reservoir at temperature Thot to a reservoir at temperature Tcold . Originally the cylinders are connected in series and the rate of heat transfer is H. If the cylinders are connected in parallel instead, then what would be the rate of heat transfer?
Six kilograms of liquid water at 0° C is put into the freezer compartment of a Carnot refrigerator. The temperature of the compartment is -15.3° C, and the temperature of the kitchen is 24.9° C.
