0.004 mole of an ideal gas has a volume 0.200 L and 0.500 atm at point a. It then evolves to point b such that its pressure is 2.00 atm in an isochoric process. Finally, the pressure of the gas reduces to 0.500 atm at point c, in an isothermal process. Find the volume at point c and the temperature at each point.
