adhension between water and glass molecules is greater than the sdhension between water molecules
- cohension between water molecules is greater then the adhension between glass and water molecule
- molecules of water near the glass move faster than the molecules at the centre of the tube
- molecules of water at the water-air boundary are often attracted to the centre of the tube
- weight of the water pulls the centre part of the surface down
