![]() The melting point of a substance depends on pressure and is usually specified at standard pressure. Below the melting point, the solid is the more stable state of the two, whereas above the liquid form is preferred. At the melting point the two phases of a substance, liquid and vapor, have identical free energies and therefore are equally likely to exist. Adding a heat will convert the solid into a liquid with no temperature change. The melting point also defines a condition in which the solid and liquid can exist in equilibrium. The melting point of a substance is the temperature at which this phase change occurs. In general, melting is a phase change of a substance from the solid to the liquid phase. Since it is difficult to measure extreme temperatures precisely without bias, both have been cited in the literature as having the higher boiling point. Both the boiling points of rhenium and tungsten exceed 5000 K at standard pressure. In the periodic table of elements, the element with the lowest boiling point is helium. On the other hand, water boils at 350☌ (662☏) at 16.5 MPa (typical pressure of PWRs). A liquid at high pressure has a higher boiling point than when that liquid is at atmospheric pressure. A liquid in a partial vacuum has a lower boiling point than when that liquid is at atmospheric pressure. When considered as the temperature of the reverse change from vapor to liquid, it is referred to as the condensation point.Īs can be seen, the boiling point of a liquid varies depending upon the surrounding environmental pressure. The pressure at which vaporization (boiling) starts to occur for a given temperature is called the saturation pressure. Below the boiling point, the liquid is the more stable state of the two, whereas above the gaseous form is preferred. At the boiling point the two phases of a substance, liquid and vapor, have identical free energies and therefore are equally likely to exist. Any addition of thermal energy results in a phase transition. The liquid can be said to be saturated with thermal energy. The temperature at which vaporization (boiling) starts to occur for a given pressure is also known as the saturation temperature and at this conditions a mixture of vapor and liquid can exist together. The boiling point of a substance is the temperature at which this phase change (boiling or vaporization) occurs. In general, boiling is a phase change of a substance from the liquid to the gas phase. Note that, these points are associated with the standard atmospheric pressure.
