Nonexpansion Work vs. Expansion Work

Postby MCracchiolo 1C » Sat Jan 13, 2018 3:20 pm

What is the difference between non expansion work and expansion work, and what does it mean when the book says "at constant volume and no non expansion work" where the change in internal energy is equal to q?

Expansion work is work that changes the volume, while nonexpansion work is work that doesn't change the volume. I think that the meaning of constant volume and no nonexpansion work means that their is no other work done. That's why it is equal to q, because the transfer/change of energy is happening through heat.
