What else could happen to water walls?

Correct Answer

Water walls would not work because water is a liquid that flows and does not keep its shape.

If walls were made of water, they would flow away, spill, and collapse. Water cannot hold itself upright like solid materials such as bricks, stones, or wood.

Additionally, water would evaporate over time, freeze in cold weather, or leak through any container.

Walls need to be made of solid materials that maintain their shape and provide structural support.

Explanation

The chapter on Page 11 uses Khushi's playful statement 'Walls - can't be made of water' to introduce the concept of states of matter. Water is a liquid that flows and does not maintain its shape, while solids like stones, bricks, and wood keep their shape and are suitable for building walls.
