Homework Statement
In a waterfall about 20 billion liters of water per hour drop about 110 m. What is the increase of the water temperature, assuming that the entire gain of heat is transferred to the water?
Homework Equations
I'm more curious about the question in itself. Perhaps I'm missing something but how could there be a heat difference or a heat transfer when the water is falling, increasing kinetic energy and actually due to the speed the water is being cooled? I don't think I'm understanding the question properly or the question is badly worded but can someone explain what exactly is going on here?
The Attempt at a Solution
The solution I believe is straight forward and it just involves potential energy = heat energy BUT I want to thoroughly understand the exercise/the physics behind it before just plugging in some numbers into a few formulas and getting a right answer.
