If 1.000 kcal of heat is added to 1.700 L of oxygen in a cylinder at constant pressure of 1.00 atm, the volume increases to 2.100 L. Calculate the total energy change for this process.

1000 kcal = 4184 kJoules is added to the mixture, but some work is done by the expanding gas. The work is equal to P x (change in volume). Make sure P is in Newtons/m^2. Then P x 9change in volume0 will be in Joules. Remember to convert 1 atm to Newtons/m^2 (Pascals)
The difference between heat added and work done is the internal energy change of the oxygen.
