Boiling point

Melting Point and Freezing Point. Pure, crystalline solids have a characteristic melting point , the temperature at which the solid melts to become a liquid. The transition between the solid and the liquid is so sharp for small samples of a pure substance that melting points can be measured to 0. The melting point of solid oxygen, for example, is Liquids have a characteristic temperature at which they turn into solids, known as their freezing point. In theory, the melting point of a solid should be the same as the freezing point of the liquid. In practice, small differences between these quantities can be observed.

Nabr Intermolecular Forces. Whoever wrote the original question is a bit weak on bonding theories. Equation : Intermolecular forces occur during hydration of ions are ion-dipole forces, which were stronger than hydrogen bonding. State and identify the three intermolecular forces including London dispersion forces and how they affect melting points, dipole forces, and hydrogen bond forces What kind of intermolecular forces does Br- in water experience; london dispersion, dipole-dipole, hydrogen bonding, ion-dipole? Density: The density of alkanes increases with the increase in molecular mass which increases with the increase in the number of carbon atoms.

Boiling point , temperature at which the pressure exerted by the surroundings upon a liquid is equaled by the pressure exerted by the vapour of the liquid; under this condition, addition of heat results in the transformation of the liquid into its vapour without raising the temperature. At any temperature a liquid partly vaporizes into the space above it until the pressure exerted by the vapour reaches a characteristic value called the vapour pressure of the liquid at that temperature. As the temperature is increased, the vapour pressure increases; at the boiling point, bubbles of vapour form within the liquid and rise to the surface. The boiling point of a liquid varies according to the applied pressure; the normal boiling point is the temperature at which the vapour pressure is equal to the standard sea-level atmospheric pressure mm [ At higher altitudes the temperature of the boiling point is lower.
