How can you distinguish cohesion and adhesion?

• Cohesion keeps the water molecules together. Surface tension pulls the water

  molecules to other molecules such as the xylem.

• Adhesion keeps the water molecules together. Cohesion pulls the water molecules

  to other molecules such as the xylem.

• Cohesion keeps the water molecules together. Adhesion pulls the water molecules

  to other molecules, such as xylem.

• Surface tension keeps the water molecules together. Adhesion pulls the water

  molecules to other molecules such as the xylem.
