How can we label the diagram? **Phase Diagram for Carbon Dioxide (CO2)****Diagram Explanation:**The diagram represents the phase changes of carbon dioxide based on pressure (in atm) and temperature (in °C). It includes regions for solid, liquid, and gaseous CO2.- **Axes:** - The vertical axis represents pressure, measured in atmospheres (atm). - The horizontal axis represents temperature in degrees Celsius (°C).- **Regions:** - The blue shaded region indicates the conditions under which CO2 exists as a solid. - The pink shaded region represents the liquid phase of CO2. - The area to the right of the diagram, outside any shading, indicates the gas phase.- **Key Points:** - **Triple Point:** The intersection where all three phases (solid, liquid, and gas) coexist. It's marked clearly on the diagram. - **Equilibrium Lines:** - The line separating the solid and gas phases represents the solid-gas equilibrium. - The line between the solid and liquid phases indicates solid-liquid equilibrium. - The curve demarcating the transition between liquid and gas is the liquid-gas equilibrium.**Answer Bank:**Adjacent to the diagram, an "Answer Bank" is provided to label the diagram:- solid-gas equilibrium- gas- solid-liquid equilibrium- liquid-gas equilibriumThis diagram is a simplified phase diagram used to study the behavior of carbon dioxide under varying temperature and pressure. Understanding this diagram is essential for comprehending the conditions for phase changes in CO2.

Phase diagram: The phase diagram represents the different phases of the substance and the pressure and temperature at which thermodynamically distinct phases (such as solid, liquid, or gaseous states) occur and coexist at equilibrium.Triplet point: The point in the phase diagram at which three different phases coexist at equilibrium is known as the triplet point. The three phases of the matter and different equilibriums in the given phase diagram are as follows:
