Homework Statement
Assume nitrogen gas (N2) is an ideal gas. n = 7.57 moles of N2 gas are heated isobarically (at constant pressure) from temperature To = 18.6 oC to temperature Tf = 50.9 oC. Find:
c) ΔIE, the change in internal energy of the N2 gas
Homework Equations
Change in IE = Change in KE = (3/2)nRΔT
The Attempt at a Solution
Since this is an ideal gas, only Kinetic Energy considerations need to be accounted for, or,
Change in KE = Change in IE = (3/2)(7.57)(8.314)(50.9-18.6) = 3,049.29 Joules
Once again, thanks for the help! I think I am doing the correct thing, or am I going crazy? =)
