Question 12

Q12) Explain the terms vaporization and boiling point.

Solution:

The process of change of liquid to vapours on heating is called vaporization. When we heat a liquid, the temperature tends to rise till the liquid starts changing into vapours and then the temperature remains constant for sometime, even though we are supplying heat. This heat supplied is being used to change the state of the substance from liquid to vapour. The temperature at which a liquid starts changing into vapours or gas at constant temperature is called boiling point.
