a) For a reversible isothermal expansion to 10.0 dm^3. b) If you opened a valve

a) For a reversible isothermal expansion to 10.0 dm^3.
b) If you opened a valve and allowed the system to expand at a constant pressure of 1 bar to regain equilibrium.
c) If you open a valve to have the gas to expand into a second evacuated chamber that has a volume of 10.00 dm^3 and allowed the new system to regain equilibrium.
d) If you reversibly expand the gas at constant pressure to a final volume of 10.0 dm^3.
e) For an adiabatic expansion to 10.0 dm^3.
f) If you reversibly change the pressure of the gas at constant volume to a final pressure of 1 bar.
