Which of the following explains the concave meniscus of water in a glass tube?
-
The adhesion between water and glas is greater than the cohesion between water molecules
- The cohesion between water molecule is greater than the adhesion between glass and water
- The molecules of water in the glass are moving faster than the molecules in the other parts
- The molecules of water at the water-air boundary are often attracted to the center of the tube
- The weight of the water pulls the central part of the surface down
