One mole of an Ideal Gas, for which Cv,m = 3/2R, initially at 20.0 C and 1.00 x106 Pa undergoes a two-stage transformation: Stage 1: The gas is expanded isothermally and reversibly until the volume doubles. Stage 2: Beginning at the end of the first stage, the temperature is raised to 80.0 C at constant volume. For each stage, calculate the final pressure, heat(q), work(w), change in internal energy (ΔU), and enthalpy (ΔH). Calculate the total q, w, ΔU, and...

7) A 1.20 mole sample of an ideal gas at 28.0°C expands isothermally from an initial volume of 24 dm to a final volume of 75 dm3. Calculate w for the following processes: (a) an expansion against an external pressure of 0.5x 105 Pa (b) a reversible expansion. Please give these quantities in joules. This may involve unit conversion(s).

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.

Suppose that we allow 3.50 mol of an ideal gas with Cv=5R/2 to expand isothermally and reversibly from 100 atm, 10 L to 10.0 atm and then the gas is allowed to expand adiabatically and reversibly to a final pressure of 1.00 atm. Calculate q, w, ΔU and ΔH for each step and the total values for the two steps. Suppose now that the processes are carried out irreversibly with pressure dropping discontinuously from 100 atm to 10.0 atm in...

A cylinder with a piston contains 0.140 mol of nitrogen at 1.88 105 Pa and 325 K. The nitrogen may be treated as an ideal gas. The gas is first compressed isobarically to half its original volume. It then expands adiabatically back to its original volume, and finally it is heated isochorically to its original pressure. PLEASE do B and C and don't don't forget to show all the steps specially for B becuase I don't know how to do...
