work, heat, enthalpy and internal energy
« on: April 11, 2011, 06:52:57 AM »
Hi everyone,
I hope someone can help me with this question. I have read on the topic but I thought if I could see someone do this example I will be able to follow:

When 10.00 mol N2 is heated at a constant pressure of 5.00atm, its temperature increases from 298 K to 345 K. Given that the molar heat capacity of N2 at constant pressure is 29.125 J/ K/ mol, calculate q, delta H, and delta U.

Well, it looks like you need to start with some equations.  So, do you know the equations for:
-The heat at constant pressure
-Work for expanding a gas-and the ideal gas law would help you out too. 

I'll check back a bit later to see what you have...
