Heating Curve of a Substance Phase Diagram of Water and Carbon Dioxide 4 PICS 1 What are the phase diagrams of water and carbon dioxide ... Each line represents phase changes between respective boundaries. The triple point is where all the phases are at equilibrium. Phase changes are usually isothermal, so temperature is constant until every molecule has attained high enough heat (e.g. kinetic energy) to surpass the intermolecular forces characteristic of each phase at varying strengths. 12.4: Phase Diagrams - Chemistry LibreTexts The Phase Diagram of Carbon Dioxide In contrast to the phase diagram of water, the phase diagram of CO 2 (Figure 12.4. 3) has a more typical melting curve, sloping up and to the right. The triple point is −56.6°C and 5.11 atm, which means that liquid CO 2 cannot exist at pressures lower than 5.11 atm.

Phase diagram of carbon dioxide. The solid-liquid curve exhibits a positive slope, indicating that the melting point for CO 2 increases with pressure as it does for most substances. Notice that the triple point is well above 1 atm, indicating that carbon dioxide cannot exist as a liquid under ambient pressure conditions. Phase diagram of water in carbon nanotubes | PNAS A phase diagram of water in single-walled carbon nanotubes at atmospheric pressure is proposed, which summarizes ice structures and their melting points as a function of the tube diameter up to 1.7 nm. The investigation is based on extensive molecular dynamics simulations over numerous thermodynamic states on the temperature-diameter plane.
