In this Physics tutorial, you will learn:

  • The meaning of adhesive and cohesive forces
  • The conditions for the existence of adhesive and cohesive forces
  • What shape does a certain surface take due to adhesive and cohesive forces?
  • What is surface tension?
  • Where does surface tension differ from surface tension force?
  • What is capillarity?
  • How to calculate the maximum height a liquid can rise in narrow tubes?

Introduction

Why water drops have a spherical shape?

Why mercury looks like a liquid when it is in glass containers while when it falls on the ground looks like grains taking spherical shapes?

How does water rises up to the highest leaves in trees?

How does blood circulates in all our body even if we are standing up?

How do the soap bubbles form?

Why water seems as sticking on the sides of a glass container?

Why water surface in narrow tubes has a round shape instead of plane shape it has in wider containers?

I am sure all these questions have arisen in your mind at least once. Nature is interesting; not always things are as they look. Therefore, here we are to explore its hidden aspects and explain the mysteries of micro-world.

This tutorial discusses concepts like adhesive and cohesive forces, surface tension and capillarity, which are related to the behaviour of liquids and other properties of matter we have explained earlier in the previous sections. Although such concepts are somehow bypassed by the actual school curriculum, they are very important in explaining the behaviour of liquids. Therefore, along with the explanation of these new concepts, we will also review some matter properties you already know. But as a proverb says: "Repetition is the mother of skills", isn't it?
