The melting point of a crystalline solid is the temperature range at which it changes state from solid to liquid. See also: Melting Point
The boiling point of a liquid is the temperature at which the vapor pressure of the liquid equals the environmental pressure surrounding the liquid. See also: Boiling Point
The flash point of a flammable liquid is the lowest temperature at which it can form an ignitable mixture in air. See also: Flash Point
Specific gravity is defined as the ratio of the density of a given substance to the density of water, when both are at the same temperature. See also: Specific Gravity
The refractive index (or index of refraction) of a medium is a measure for how much the speed of light (or other waves such as sound waves) is reduced inside the medium. See also: Refraction Index
