Question

Name the following.

Force between water molecules.

Answer 1

1. When water is lost from the mesophyll cell of leaves to intercellular spaces, transpiration occurs.
2. This results in a negative water potential that creates an upward pull of the water column.
3. This pull is due to the tendency of water molecules to remain joined together during transpiration.
4. The property of water molecules to remain joined together is because of their ability to form hydrogen bonds and such force of attraction is called cohesion force.

Therefore, the force between water molecules is called cohesion force.
