उत्तर
“Change of liquid to vapours (gas) on heating at constant temperature is called VAPORIZATION.”
When we heat a liquid, the temperature starts rising till it starts changing into vapours, and then the temperature remains constant for some time, though we are supplying heat. This heat supplied is being used to change every molecule of liquid into vapours and temperature does not rise till the whole of liquid is changed into vapours.
