Question

Read the given statements and select the correct option. 

1. Water molecules have very weak adhesive and cohesive forces of attraction.
2. Water can easily rise in capillaries due to high surface tension and high adhesive and cohesive force.

Which of the above statement(s) is/are correct?

Options

• Only I

• Both I and II

• Only II

• Neither I or II

Answer 1

Only II

Explanation:

Statement II is correct.

Water is capable of rising in capillaries due to high surface tension and high adhesive and cohesive forces.

Statement I is incorrect.

Both the adhesive and cohesive forces in the case of water are high, thus it gets the feature of sticking and binding to surfaces and to other water molecules.
