A 0.825 mol sample of NO2(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 19.3 K. Assuming ideal gas behavior, calculate the amount of heat (?) in joules required to affect this temperature change and the total change in internal energy, Δ?. Note that some books use Δ? as the symbol for internal energy instead of Δ?.
