During summer, Boojho carries water in a transparent plastic bottle to his school. One day he left his bottle in the school. The bottle still had some water left in it. The following day, he observed some water droplets on the inner surface of the empty portion of the bottle. These droplets of water were formed due to
(a) boiling and condensation
(b) evaporation and saturation
(c) evaporation and condensation
(d) condensation and saturation
Correct Answer: (c) evaporation and condensation
Explanation: Due to high temperature in summers, the water gets heated in plastic bottle and evaporates. The vapours hit the lid of the bottle and condensed to form water droplets which get collected on the empty portion of the bottle.
