The vapor pressures of solid chlorine are 3.52 torr at -110 Celsius and 0.776 torr at -120 Celsius. The vapor pressures of liquid chlorine are 27.6 torr at -90 Celsius and 58.7 torr at -80 Celsius. Compute delta H of vaporization, sublimation, and fusion and the temperature as well as pressure at the triple point.
