Temperature The triplewpoint. The temperature and pressure at which all three states exist in equilibrium. A point where the substance can go through deposition at a given temperature and pressure. A point where the substance can exist as a gas under a given temperature and pressure. The critical point. A point where the substance can 1. Point 1 melt at a given temperature and pressure 2. Point 2 A point where the substarre can exist as a solid under a given temperature and pressure. A point where the substance can exist as a supercritical fluid under a given temperature and pressure. A point where the substance can boil/vaporize at a given temperature and pressure. A point where the substance can go through deposition at a given temperature and pressure. A point where the substance can freeze at a given temperature and A point where the substance can freeze at Sgiven temperature and pressure. A point where the substance can go through condensation at a given temperature and pressure. A point where the substance can exist as a liquid under a given temperature and pressure. The point that signifies the critical temperature and critical pressure
