A block of copper of mass 500g and initial temperature at 293 k is in thermal contact with an electric heater of resistance 1.00kohm and negligible mass. a current of 1 A is passed for 15 s. calculated the change in entropy of the copper taking C=24.4j/kmol. the experiment is then repeated with the copper immersed in a stream of water that maintains its temp at 293. Calculate the change in entropy of the copper and the water in this case.
