Question

suppose you push down on the handle of a bicycle pump with a force of 20N .the handle moves 0.3m and there is no heat between the pump and its surroundings what is the change in thermal energy of the bicycle pump?

Answer 1

6 Joules

Step-by-step explanation:

The change in internal energy must be equal the work done by pushing the handle with a 20 N force a distance of 0.3 meters. That is:

Change in internal energy = Work = 20 * 0.3 J = 6 Joules
