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 0.1oC. The melting point of solid oxygen, for example, is -218.4oC.

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.

It is difficult, if not impossible, to heat a solid above its melting point because the heat that enters the solid at its melting point is used to convert the solid into a liquid. It is possible, however, to cool some liquids to temperatures below their freezing points without forming a solid. When this is done, the liquid is said to be supercooled.

The information on melting point, boiling point, and flammability might be useful to materials scientists as:

What is Melting point?

The temperature for the pure substance at which the liquid and solid phase exist in equilibrium condition

What is Boiling point?

The temperature at which the vapour pressure of the liquid is equal to the atmospheric pressure.

What is flammability?

Flammability is the ability of a substance such as solid, liquid and gases to ignite in air if source of ignition is applied.

Material scientist apply the knowledge of physical and chemical properties of different compounds to synthesize new product or improve existing ones.

Hence to know the knowledge about melting point, boiling point, flammability might be necessary conditions for material scientist.
