States of matter for  class 5  (Points to remember)

What is matter?

Anything that has weight and occupies space is called matter.

Molecules are particles of which matter is made.

Atoms: Molecules are made up of still smaller units called atoms and atoms are the building block of matter.

Physical change is a change in which no new substance is formed. E.g water on cooling changes into ice. If this ice is heated, it changes into the water again.

Chemical change is a change in which a new substance is formed. E.g when a paper is burnt, it changes into ash, which is a new substance and we cannot get back the piece of paper back.
