Highest boiling point meaning
WebThe melting point (or, rarely, liquefaction point) of a substance is the temperature at which it changes state from solid to liquid. At the melting point the solid and liquid phase exist … Web30 de nov. de 2024 · Notice from this boiling point definition that if the surrounding pressure varies, so does the vapor pressure. That is, the boiling point varies with pressure. The higher the pressure, the higher the boiling point, and vice versa. Water boils at 100 °C (212 °F) at sea level (0 m), where pressure is higher. However, at higher altitudes, hence ...
