1. The problem statement, all variables and given/known data Rubbing your hands together warms them by converting work into thermal energy. If a woman rubs her hands back and forth for a total of 10 rubs a distance of 7.50 cm each and with a frictional force averaging 45.0 N, what is the temperature increase? The mass of tissue warmed is only 0.100 kg, mostly in the palms and fingers. 2. Relevant equations work = force * distance 3. The attempt at a solution i can find the work, but after that I don't know how to connect that to temperature change.
