Show answer and explanation
Correct answer: (c) The change of vapour into liquid
Explanation
Condensation is the change of a vapour (gas) into a liquid when it cools, as water vapour forms dew, fog and clouds, or droplets on a cold glass.
It is the reverse of evaporation. A gas turning straight into a solid is deposition, and a solid turning into a liquid is melting.
