Answer
The change from liquid to gas (or vapour) phase on absorption of heat at a constant temperature is called boiling or vaporisation.
The particular temperature at which vaporisation occurs is known as the boiling point of liquid.
Volume of water increases when it boils at 100° C. 1 cm3 of water at 100 ° C becomes 1760 cm3 of steam at 100 ° C.
