A 0.721 mol sample of N2(g) initially at 298 K and 1.00 atm is held at constant volume while enough heat is applied to raise the temperature of the gas by 11.9 K. Assuming ideal gas behavior, calculate the amount of heat in joules (q) required to affect this temperature change and the total change in internal energy, ?U. Note that some books use ?E as the symbol for internal energy instead of ?U.
