A 155 g -g sample of steam at 100°C is emitted from a volcano. It condenses, cools, and falls as snow at 0°C. (For water, 80. cal (334 J) is needed to melt 1 g of ice or must be removed to freeze 1 g of water and 540 cal (2260 J) is needed to convert 1 g of water to vapor at 100°C.) How many kilojoules of heat were released?
