Question A snow maker at a resort pumps 150 kg of lake water per minute and sprays it into the air above a ski run. The water droplets freeze in the air and fall to the ground, forming a layer of snow. If all of the water pumped into the air turns to snow, and the snow cools to the ambient air temperature of -4.1°C, how much heat does the snow-making process release each minute? Assume the temperature of the lake water is 12.3°C, and use 2.00×103 J/(kg·C°) for the specific heat capacity of snow.
