Multiple choice

A water molecule has a highly rigid structure with all bonds being in precise measurement, yet water acquires the shape of the container it is put in. What is the reason behind this?

  1. The water molecules are indeed rigid, but in liquid state, the hydrogen bonding with the neighbouring water molecules is flexible.

  2. The water molecules in liquid state become flexible so as to acquire the shape of the container.

  3. The water molecules have a natural tendency of shape adaptability.

  4. Water’s dielectric constant makes the liquid state very less viscous to allow flexibility.

A Correct answer
Explanation

The hydrogen bonding in the water molecules is the cause of flexibility of the liquid and the same is the reason for water being solid in ice state.
