A sample of 1.3 mol of CO2 (g) is placed in a 5.0 L rigid container at an initial temperature is 300 K. When 6.98 kJ of heat is added to the system (at constant volume), the temperature rises to 353 K. Calculate q, w, ∆U, ∆H, and CV.

The molar heat capacity of O2(g) at constant pressure, is 31.2 J/(K mol) around room temperature. 2.5 mol of O2(g) is heated at constant pressure from 265 K to 310 K. Calculate q, w, ∆H, and ∆U.

A sample of 5.0 mol CO2(g) is originally confined in 15 dm3 at 280 K and then undergoes adiabatic expansion against a constant pressure of 78.5 kPa until the volume has increased by a factor of 4.0. Calculate q, w, delta T, and delta U, and delta H. (The final pressure of the gas is not necessarily 78.5 kPa.) If the enthalpy you calculate does not equal -4.5 kJ and the temperature change - 24 K, you made a mistake.
