1. 35 g of liquid water at 45 c is placed in a refrigerator, which cools the water to 5 c how much energy did the refrigerator remove from the water.
2. A 200-gram aluminum water bottle is at room temperature (18 C). If you fill it with cold water, the bottle will lose 400 calories of thermal energy. What will the temperature of the bottle be then?
3. How much energy must 5 g ice cube (temperature 0 C) absorb in order to melt?
4. 48 g of molten (liquid) aluminum at a temperature of 659 C is poured into a mold. How much energy does the aluminum lose as it solidifies?
