One litter of iodine vapour at 0.04 atm pressure and 150C is isothermally compressed. a. Determine the nature of the first phase change that eventually occurs in the system as a result of this process, and b. determine the pressure st which this phase change occurs. If the system had been cooled at constant volume from its initial state, c. determine the nature of the first phase change that would have occued and d. the temperature (to within +,- C) and e. the pressure at which this phase change would have started. Assume the iodine vapor behaves as an ideal gas. An iterative approach might be needed for parts c. through e.
