Melting point

Boiling point

1) Melting point is the tempreture at which a solid turns into a liquid. Boiling point is the temperature at which the vapour pressure of a liquid is equal to the external pressure on that liquid.
2) A solid states changes into a liquid state.  A liquid state changes to its gaseous state.
3) No relation with vapor pressure of the substance. At boiling point, the vapor pressure of the liquid is equal to the pressures of surroundings.
4) Pure crystalline solid is a characteristic of melting points. liquid is a characteristic of the boiling points.
5) Vapour pressure are form when solid substance turn into liquids. Vapour pressure of the external pressure surrounding the liquid.
6) There is a no bubble formation. Formation of the bubbles inside the liquid.
7) The melting point of solid oxygen is 218.4 Degree celsius. The normal boiling of water is 100 Degree celsius.
