What happens when water is heated to 100°C? How you will get the water back?
When water is heated to 100°C, boiling of water takes place.
Boiling or Vaporization: The process due to which a liquid changes into a gaseous state by absorbing heat energy is called boiling.
We can get water back from vapours by the process of condensation.
Condensation or Liquefaction: The process due to which a gas changes into a liquid state by giving out heat energy is called condensation.
