P3B.7 A block of copper of mass 500 g and initially at 293K is in thermalcontact with an electric heater of resistance 1.00 kΩ and negligible mass. Acurrent of 1.00A is passed for 15.0 s. Calculate the change in entropy of thecopper, taking Cp,m = 24.4 JK−1mol−1. The experiment is then repeated with thecopper immersed in a stream of water that maintains the temperature of thecopper block at 293K. Calculate the change in entropy of the copper and thewater in this case.P3B.8 A block of copper (Cp,m = 24.44 JK−1mol−1) of mass 2.00 kg and at0 °C is introduced into an insulated container in which there is 1.00molH2O(g) at 100 °C and 1.00 atm. Assuming that all the vapour is condensed toliquid water, determine: (a) the final temperature of the system; (b) the heattransferred to the copper block; and (c) the entropy change of the water, thecopper block, and the total system. The data needed are given in ExerciseE3B.7a.

The protein lysozyme unfolds at a transition temperature of 75.5 °C and the standard −1 enthalpy of transition is 509 kJmol . Calculate the entropy of unfolding of lysozyme at 25.0 °C, given that the difference in the constant pressure heat capacities upon unfolding is 6.28 kJK−1mol−1 and can be assumed to be independent of temperature. Hint: Imagine that the transition at 25.0 °C occurs in three steps: (i) heating of the folded protein from 25.0 °C to the transition temperature, (ii) unfolding at the transition temperature, and(iii) cooling of the unfolded protein to 25.0 °C. (Note: Because the entropy is a state function, the entropy change at 25.0 °C is equal to the sum of the entropy changes of the steps.)
