How can you understand those slide calipers has an instrumental error?
Kinetic theory of molecules is based upon these postulates:
- Any substance is made of numerous small particles. These are known as
molecules. - Molecules are so small that they are considered point-like.
- The particles are always moving.
- In the case of gases, the molecules remain very distantly, so it can be said
that they do not feel any attractive or repulsive force. In the case of
liquid, though they remain away from each other, they face the shape of the
container. For solid objects, they remain close as they face a strong
attraction force, and thus they have their own shape and size. - For gases and liquids, the particles move randomly as they collide with each
other and the wall of the container.
