A snow maker at a resort pumps 130 kg of lake water per minute and sprays it

Question:

A snow maker at a resort pumps 130 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 the water pumped into the air turns to snow, and the snow cools to the ambient air temperature of -7.0 oC, how much heat does the snow-making process release each minute? Assume that the temperature of the lake water is 12.0 oC, and use 2.00 × 103 J / (kg · Co) for the specific heat capacity of snow.
