### Final Temperature at Constant Pressure, and then at Constant Volume

Posted:

**Fri Feb 01, 2019 3:52 pm**Hey guys,

I am working on problem 4C.3, which asks to calculate the final temperature and the change in enthalpy when 765 J of energy is transferred as heat to 0.820 mol Kr (g) at 298 L and 1.00 atm.

I know how to calculate the final temperature and enthalpy with this information but I am unsure of how to calculate that with constant pressure and then with constant volume. If someone could explain to get me started it would be much appreciated!
