Use the phase diagram given here to answer the following questions:

(a) In what phase is the substance found at room temperature and 1.0 atm pressure?
(b) If the pressure exerted on a sample is 0.75 atm and the temperature is −114°C, in what phase does the substance exist?
(c) If you measure the vapor pressure of a liquid sample and find it to be 380 mm Hg, what is the temperature of the liquid phase?
(d) What is the vapor pressure of the solid at−122°C?
(e) Which is the denser phase—solid or liquid? Explain briefly.
