For each system listed in the first column of the table below, decide (if possible) whether the change described in the second column will increase the entropy S of the system, decrease S, or leave Sunchanged. If you don't have enough information to decide, check the "not enough information" button in the last column. Note for advanced students: you may assume ideal gas and ideal solution behaviour.

I took out an ice cube from the -10°C freezer and wanted to add it to the drink, but was immediately called away and forgot to add it to the drink. When I came back, I saw that the ice cube had completely melted into water at a room temperature of 25°C. Assuming that the ice cube is exactly 2 mole, and regard this ice cube as a system, try to calculate the change of enthalpy and entropy (△H,△S) of the system. Let the heat capacity of water be 25 JK-1mol-1, the heat capacity of ice be 15 JK-1mol-1 and the heat of melting of ice △Ĥfus = 6 kJ/mol.
