उत्तर
CONDENSATION :
“The change of vapours on cooling at a fixed temperature to liquid is called condensation.”
Condensation is the change of physical state of matter from gaseous phase into the liquid phase.
It is a process in which water vapour (gaseous form) in the air changes into liquid water when it touches a cooler surface. When the water in the air comes in contact with a cold surface, it condenses to form water droplets. This phenomenon is known as condensation. The reverse of condensation is Evaporation reaction.
Example: When water vapours at 100°C are cooled they change into water (liquid).
