   What is the boiling point of a substance?

   • The boiling point of a substance is the temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid and the liquid changes into a vapor. The boiling point of a liquid varies depending upon the surrounding environmental pressure.

   What is the boiling point of a liquid?

   • The boiling point corresponds to the temperature at which the vapor pressure of the liquid equals the surrounding environmental pressure. Thus, the boiling point is dependent on the pressure. Boiling points may be published with respect to the NIST, USA standard pressure of 101.325 kPa (or 1 atm ), or the IUPAC standard pressure of 100.000 kPa.

   What is a boiling point in evaporation?

   • The formal definition in science is that boiling point is the temperature where the vapor pressure of a liquid equals the vapor pressure of its environment. At this temperature, the liquid changes into the vapor (gas) phase. In both boiling and evaporation, a liquid transitions into a vapor.

   Jan 23, 2023 · The melting points of crystalline solids cannot be categorized in as simple a fashion as boiling points. The distance between molecules in a crystal lattice is small and regular, with intermolecular forces serving to constrain the motion of the molecules more severely than in the liquid state.
