Question

describe am experiment to show that matters is composed of particles?

Answer 1

Imagine that someone enters a room wearing strong perfume or after-shave. This is because tiny particles are given off from the perfume. It evaporates. We can't see the particles that escape from its surface because they are so small. But they must be there because we can soon smell the scent in every corner of the room. This ability of a scent to diffuse through the air in a room like this is evidence that the scent – and other liquids and gases – is made up of tiny particles
