Question
Frustrated with equation manipulation, and I have no idea ifI'm doing this right?Any help is greatly appreciated!
A snow maker at a resort pumps 130 kg of lake water per minute andsprays 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 snowcools to the ambient air temperature of -7.0 °C, how much heatdoes the snow-making process release each minute?
Assume that the temperature of the lake water is 12.0 °C, anduse 2.00 × 103 J/(kg · C°) for thespecific heat capacity of snow. Frustrated with equation manipulation, and I have no idea ifI'm doing this right?

Explanation / Answer
Okay, Figured this out on my own, eventually. There are three Q(heat values) and add them together. Q1= Mass(water)*specific heat capacity(water)*change intemp.(12-0) Q2=Mass(water)*Latent Heat fusion(water) Q3=Mass(water/snow)*spec.heat cap.(snow)*change temp.(0-(-7)) Use the 130kg value for mass, add them all together and solve. (I was under alot of stress when I asked, and apparently don'tthink clearly when stressed.)
