Question

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. evaporation and condensation​
• B. evaporation and saturation​
• C. condensation and saturation​
• D. boiling and condensation​

Answer 1

The correct option is A evaporation and condensation​

In summers, the water in the plastic bottles gets heated and evaporates. This evaporated water collides with the cover of the bottle and gets condensed to form water droplets. These water droplets then get collected on the empty portion of the bottle. ​

The droplets of water on the inner surface of the bottle were formed due to evaporation and condensation. ​
