Concept of Matter
Explain concept of matter
Matter
is anything that has mass and occupies space. Therefore, anything
around us provided it has mass and can occupy the space, is termed as
matter. There are many kinds of matter. Can you mention some? The word
matter is used to cover all the substances and materials from which the
earth and universe is composed of. These include all materials around us
such as water, soil, plants, animals, air, clothes, etc.
Any
particular kind of matter is called a substance. Substances include
elements and compounds. An element is a substance which is the limit of
chemical analysis. When two or more elements are combined chemically, a
compound is formed. Matter is made up of atoms, ions or molecules. You
will learn more about this later.
