In what phase is co2 at 25 atm and −65 °c
Web21 aug. 2024 · When the temperature of a mass of solid CO 2 (at 10 atm pressure and at –65°C) is increased, it changes to the liquid phase and then to the vaporous phase. It forms a line parallel to the temperature axis at 10 atm. The fusion and boiling points are given by the intersection point where this parallel line cuts the fusion and vaporisation curves.
