Practice Problem

Postby Michelle Steinberg2J » Mon Mar 12, 2018 3:29 pm

I'm not sure what equation to use for this problem -- there's so much information.
It would be really helpful if someone could walk through the steps. Thank you!

I think it's easier to start with part b and c
b) Remember that q=moles (molar heat capacity) (delta T). You have all the information, so just substitute to find q.

a/c) Delta U = q + w
So all that is left is you need to solve for work since q was solved above. The work is from the volume change. Internal energy can be found by substituting q and w.
