Problem 4. (20 points) A block of ice with mass m = 2 kg at the triple point temperature m Ti = 0.01°C (state 1) is taken out of a freezer and put in a bucket in a room where temperature is T, = 25°C. Ice slowly melts until there is only liquid water at temperature 0.01°C in the bucket (state 2). Using Tables B.1.1 and B.1.5 for saturated liquid and solid states find = (a) (5 points) The total heat transfer Q12 to the control mass of water from the surroundings (i.e., from air in the room) during the melting process. (b) (5 points) The entropy change for the water in this process. (c) (5 points) The net entropy change for this process, i.e., the total entropy change ASnet for the water and the surroundings. (d) (5 points) Can answers to questions (a) - (c) be found using specific heats? Explain your answer.
