Define melting point and boiling point and write their values?

Answer 1

Melting point is defined as the temperature at which a solid melts to become a liquid, the value of which depends upon the material. Boiling point is defined as the temperature at which a liquid reaches such a temperature that bubbles begin to form inside the liquid due to vapor pressure. The value at which a liquid boils depends on what the liquid you are attempting to boil, is.

Oil boils at a higher temperature than water. Antifreeze boils at another temperature altogether.

Steel, when liquid, boils at a very high temperature, while alcohol boils at a comparably low temperature.
