Question

30. Cohesion of water molecules is due to
(A) Diffusion
(B) Osmosis
(C) Surface tension
(D) Gravity​

Answer 1

Answer:

The answer is C

that's the answer

Answer 2

Option (C) Surface tension is the cause of the cohesion of water molecules.

• The ability of molecules in a substance to stick together is referred to as cohesion.
• When a substance transmits from a high concentrated area to a low concentration, then that is termed diffusion.
• From lower solute concentration to higher solute concentration, a substance movement is referred to as osmosis.
• The force that holds every subject to its center is referred to as gravity.
• The characteristic of water that prevents when an external force comes is surface tension.
