How can you explain Joule's paddle experiment without calorimetry?
I have been explaining that the work done ( by the falling weights
attached
to the paddle wheel) resulted in an increased temperature of the water
of known mass in the tank. This explanation does not require any
calorimetry.
Please believe that I am sincere in asking, " How do you explain
Joule's paddle wheel experiment WITH calorimetry?"
