Question

What is meant by boiling point? what is meant by matter? What is meant by melting point?​​

Answer 1

Explanation:

i)Boiling point, temperature at which the pressure exerted by the surroundings upon a liquid is equaled by the pressure exerted by the vapour of the liquid; under this condition, addition of heat results in the transformation of the liquid into its vapour without raising the temperature.

ii)Anything that occupy space and have mass is called matter.

iii)Melting point, temperature at which the solid and liquid forms of a pure substance can exist in equilibrium. ... More heat then will convert the solid into a liquid with no temperature change. When all the solid has melted, additional heat will raise the temperature of the liquid.
