Air in a bicycle pump is compressed by pushing in the handle. The inner diameter of the pump is 3.0 cm and the pump is depressed 20. cm with a pressure of 2.00 atm. (c) What is the change in internal energy of the system?

How would you calculate the change in internal energy if you only know the change in work, but not heat?

For this problem, q=0 therefore the 28J of work is the change in heat
