Homework Statement
I read about Joule's experiment proving the transformation of mechanical work into heat. But say I have a bowl with some water, and I start turning a spoon in it very fast, thus doing work - the water won't get hotter! What am I missing?
Homework Equations
conservation of energy
The Attempt at a Solution
I think maybe the work will simply go to movement and not to heat, but then how do you explain Joule's experiment?
