adiabatic expansion problem
« on: January 28, 2008, 10:36:12 PM »
So this is an adiabatic expansion problem and I need to find deltaH given:

w = -1200 J
deltaU = -1200 J
q = 0
Tinitial = 298K
n = 1 mole

Thank you in advance! :)

Please read the Forum Rules.  You should that show you've at least attempted to answer the problem before we will help you.

To start, what can you say about the final temperature?

That it's going to be lower than the initial temperature...

For an ideal gas, how does ΔU relate to ΔT?
