4A.3

Postby KeiannaPineda1B » Sat Feb 01, 2020 12:45 am

4A.3 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. (a) How much work is done in the compression? (b) Is the work positive or negative with respect to the air in the pump? (c) What is the change in internal energy of the system?

This question requires calculations we did not necessarily learn in class. Do you think it will be on the midterm?

The basis of the question gets to the heart of w = -P deltaV, so I would think it's fair game.

Do we have to know the conversion from this question as well?
