A 0.357 mol sample of CO2(g), initially at 298 K and 1.00 atm, is held at constant pressure while enough heat is applied to raise the temperature of the gas by 18.9 K. Calculate the amount of heat ? required to bring about this temperature change, and find the corresponding total change in the internal energy Δ? of the gas. Assume that the constant‑pressure molar specific heat for CO2(g), which consists of linear molecules, is equal to 7?/2, where ? is the ideal gas constant.
