1.	Why does the temperature of substance remain constant during its melting or boiling point
Answer» ${\bold{\blue{\underline{\red{A}\pink{ns}\green{we}\purple{r:-}}}}}$ ➝ The temperature of SUBSTANCE remain constant during its melting and boiling point because of latent heat or the heat supplied to the substance is used up in OVERCOMING the intermolecular force and therefore it doesn't show up as a rise in temperature. More Information :- Latent heat of vaporization :- The quantity of heat REQUIRED to change ONE unit mass of LIQUID into gaseous state at its boiling point or maximum temperature without any change of temperature is known as latent heat of vaporization. It is also known as latent heat of boiling of liquid. SI unit of latent heat of vaporization is j/kg. Latent heat of fusion :- The quantity of heat required to convert one unit mass of a substance from the solid to the liquid state at its melting point without changing its temperature is called latent heat of fusion.
