State the normal melting and boiling points

Reference no: EM13176853

The normal melting and boiling points of O2 are -218C and -183C respectively. Its triple point is at -219C and 1.14 torr, and its critical point is at -119C and 49.8 atm.

a) sketch the phase diagram for O2, showing the four points given and indicating the area in which each phase is stable.

b) Will O2 (solid) float on O2 (liquid)? Explain.

c) As it is heated, will solid O2 sublime or melt under a pressure of 1 atm?
