377 g of water at 81°C & 279 g of glycerin at 47°C are poured into a 427 g copper cup at 58°C. Assuming these three make up a closed (or isolated) system, determine the FINAL TEMPERATURE of the system.

A cube of ice is taken from the freezer at -9.4°C and placed in a 100 g aluminum calorimeter filled with 278 g of water at room temperature of 20°C. The final situation is observed to be all water at 15°C. What was the mass of the ice cube?

274 g of water at 2°C is added to ice at 0°C. If the final temperature of the system (which you can assume is isolated) is 0°C, determine HOW MUCH ICE MELTED.

0.4 kg of steam at 100°C is added to 2.74 kg of ice at 0°C. Determine the temperature of the mixture once thermal equilibrium is reached.

Ice cubes at 0 c are poured into a glass that contains 150 g of liquid water at 20 c. The contents of the glass are gently stirred and after short time the ice melts and the liquid cools to 0 c. No appreciable heat exchange with the environment takes place. a) calculate the entropy change of the universe (system plus environment) during the process. Cp=Cv = 4.18 kj/kgK b)if the same process were performed reversibly, how much useful work...
