Assume that all of the potential energy goes into increasing the internal energy of the water and that it takes 4186 J/kg to increase the water's temperature 1 degree celsius. If 505 kg of water falls a distance of 50.0 m, what will the temperature of the water be at the bottom of the falls?

2. PE = mgh

3. Now, Im not too sure if I did this right, because its somehow seems too simple.

I simply used the equation above and plugged in the numers, (505 x 50 x 98), which gives me 247450. So then, I divided that by 4186, which gives me 59 (degrees celsius). Then I add the 59 to the original 10, giving me 62 degrees celsius. Does that seem right? Maybe Im over simplifying it?
