A hanging weight with a mass of m = 14.0 kg falls a distance of h = 8.1 m causing paddles to turn in a tank of water. If the mass of the water is mw = 0.5 kg, what is the maximum possible change in the temperature of the water?

Best ResponseYou've already chosen the best response.0If (and that is a big "if") all of that energy lost in the change in gravitational potential energy were somehow converted into heat energy to heat water, what equation would you use to relate a heat energy input to a change in temperature of the water?
