“Draw a detailed phase diagram for carbon dioxide (CO₂) and label the regions corresponding to solid, liquid, and gas phases. Explain how increasing pressure at a constant temperature influences the phase transitions of CO₂, particularly focusing on the conditions under which it can exist as a solid or gas. Illustrate a comprehensive phase diagram for water (H₂O) and label the regions for solid, liquid, and gas phases. Describe the impact of decreasing temperature at a constant pressure on the phase of water, including the specific temperature points at which phase changes occur and the molecular behavior associated with these transitions.”
