Question:
A block of copper of mass 500 g and initially at 293K is in thermal contact with an electric heater of resistance 1.00 kΩ and negligible mass. A current of 1.00 A is passed for 15.0 s. Calculate the change in entropy of the copper, taking Cp,m = 24.4 JK−1 mol−1. The experiment is then repeated with the copper immersed in a stream of water that maintains its temperature at 293K. Calculate the change in entropy of the copper and the water in this case.
