What is condensation?

Condensation can be defined as a process where gaseous form of any matter changes to liquid form. It also includes all those reactions where 2 molecules are connected with loss of water. For example, when the water evaporates, the gaseous state i.e., the air comes in contact with the cold surface and then forms the liquid state that is water when this comes in contact with a cold surface. In simple terms, when air comes in contact with a cold surface it forms water droplets
