1) If you place the corner of a paper towel into a droplet of water, the water moves into the
paper towel. Which of the following would explain the movement of the water?
(A) surface tension; (B) cohesion; (C) adhesion; (D) Both cohesion and adhesion.

Respuesta :

Answer:

D: Both cohesion and adhesion.

Have a great day! :)

Answer:

The correct answer is (D) Both cohesion and adhesion.

Explanation:

Cohesion and adhesion is the properties of water which allow it to stick to different surface. Therefore they provide stickiness in water molecule.

Adhesion is the force that allows water to be stuck and soaked in a paper towel and move through capillary action in the paper towel and cohesion is the force that stick two water molecule together. These two forces together allow water molecules to stick a surface and move up against gravity.

Therefore, If we place the corner of a paper towel into a droplet of water, the water moves into the paper towel due to both cohesion and adhesion. So the correct answer is (D) Both cohesion and adhesion.
