Assertion: A balloon filled with water is larger in size as compared to the empty balloon. Reason: The water filled in the balloon exerts pressure on the walls of the balloon.

Understand the Problem

The question presents an Assertion and a Reason, and asks you to determine if both are true, and if the Reason correctly explains the Assertion. In this specific case, the Assertion states that a water-filled balloon is larger than an empty one, and the Reason states that the water exerts pressure on the balloon's walls.

More Information

The water inside the balloon exerts pressure on the walls equally in all directions. This pressure is what causes the balloon to expand until the elastic force of the balloon material balances the water pressure.

Tips

A common mistake is to confuse pressure with force. Pressure is force per unit area. Even a small amount of water can exert a significant pressure if it's contained within a flexible container like a balloon.
