a. While ice is melting, it absorbs 334 kJ of heat per kilogram of ice. This takes place at a constant temperature of 0°C. What is the entropy change of 4 kg of ice while it melts? b. While water is boiling, it absorbs 2257 kJ of heat per kilogram of water. This takes place at a constant temperature of 100°C. What is the entropy change of 10 kg of water while it boils? c.
