At what temperature and pressure can the solid, liquid and vapour phases of `CO_2` co-exist in equilibrium?

Answer the following questions based on the P-T phase diagram of carbon dioxide: What is the efect of decrease of pressure on the fusion and boiling point of CO_2 ?

Answer the following questions based on the P-T phase diagram of carbon dioxide: What are the critical temperature and pressure for CO_@ ? What is their significance?

Answer the following questions based on the P-T phase diagram of CO_2 CO_2 at 1 atm pressure and temperature 60^@C is compressed isothermally. Does it go through a liquid phase?

Answer the following questions based on the P-T phase diagram of CO_2 What happens when CO_2 at 4 atm pressure is cooled from room temperature at constnat pressure?

Answer the following questions based on the P-T phase diagram of CO_2 Describe qualitatively the changes in a given mass of solid CO_2 at 10 atm pressure and temperature -65^@C as it is heated upto room temperature at constant pressure.

Read the given passage and answers following questions : Emulsion: It is a colloidal mixture in which both the dispersed phase and the dispersion medium are liquids. The two or more liquids present in the mixture are generally immiscible in nature. Example: Milk. Gel: It is a colloid in which the dispersed phase i.e. liquid has combined with the dispersion medium i.e. solid to produce a semisolid material. Example: jellies. Answer the following questions : Which type of nature dispersed phase and medium exist?
