Homework Answers
When an amount of ice is
dropped into the tea, the ice will melt and then it will gain some
amount of heat and also the tea will reject some amount of heat and
mixed system will reach at equilibrium temperature.

An ice cube of mass 500 g at 0 °C is dropped into an insulated container of 1.0 kg of water that initially is at room temperature (25 °C), and eventually the system reaches equilibrium. The insulator is not perfect, so 20 kJ of heat flows from the room into the water during the process. 3. a. Calculate the entropy increase in the ice that melts into water. b. Calculate the entropy loss of the water that cools down. c....
