Question

5. Take out a cooled bottle of water from the refrigerator and keep it on a table. After some time you notice a puddle of water around it. Why?

Answer 1

• The process of conversion of water vapor into water is known as condensation.
• The temperature in the refrigerator is lower than the outside.
• So, when the cooled water bottle is kept on the table, the water vapor of the air condenses on the surface of the bottle.
• Hence, as a result, a puddle of water appears around the bottle.
