Question

activity to show that particls of matter attract each other

Answer 1

The particles of matter attract each other:

There are some forces of attraction between the particles of matter which bind them together.The force of attraction between the particles of the same substance is known as cohesion.If we take a piece of chalk, a cube of ice and an iron nail, and beat them with a hammer, we will find that it is very easy to break the piece of chalk into smaller particles, it requires more force to break a cube of ice, whereas the iron nail does not break at all even with a large force.This shows that the force of attraction between the particles of chalk is quite weak; the force of attraction between the particles of ice is a bit stronger whereas the force of attraction between the particles of iron nail is very, very strong.
