60 solid liquid 50 40 P (bar) 30 OZ gas 10 50 100 150 250 350 400 200 T(K)

The melting point of this substance at 41 bar is 190 K The boiling point of this substance is 200 K when the pressure is 2.17 bar When the substance is heated at a constant pressure of 30 bar starting at 50k and ending at 350K, the phase changes it undergoes are in order, freezing then vaporization • When the substance is kept at 200 K and the pressure on it reduced, starting at 60 bar and ending at 10 bar, the phase changes it undergoes are, in order, freezing then vaporization

The melting point of this substance at 41 bar is 190 K. The boiling point of this substance is 200 K when the pressure is 2.17 bar. at pressure of 30 bar starting at 50K a then vaporization When the substance is h melting it undergoes are, in order freezing Ⓡ vaporization When the substance is k condensation sublimation changes it undergoes ar deposition he pressure on it reduced, starting at e then vaporization
