1. Use the equipartition principle to estimate the value of γ = Cpm/CVm for gaseous N2O5. Do this calculation WITH the vibrational contribution to the energy. 2. A sample consisting of 0.15 mol of gas is compressed isothermally at 300K from 0.02m3 to 0.01m3 reversibly. Calculate w. 3. A sample consisting of 3 mol of argon (monoatomic gas), initially at P1=352kPa and T1= 320K, is cooled reversibly to 240K at constant volume. Calculate the q. 4. A chemical reaction takes place in a container fitted with a piston of cross-sectional area 20cm2. As a result of the reaction, the gas undergoes a compression, the piston is displaced by 5cm (toward the bottom of the container), pushed by an external pressure of 105Pa. Calculate the work.
