define matter ??? what is its composition
Answers
Explanation:
MATTER - DEFINITION
Matter is everything around us. Atoms and molecules are all composed of matter. Matter is anything that has mass and takes up space.
COMPOSITION OF MATTER - DEFINITION
Anything that occupies space and has mass is known as Matter. So everything that we see around us is known as Matter. Matter is basically made up of Atoms and Molecules. Depending upon its physical state, the nature of matter falls into three categories: Solids, Liquids and Gases.
1. Solids- These are the substances where the constituent particles (atoms or molecules) are held together so tightly, that it is impossible for them to move from there position. They have definite shape and fixed volume.
2. Liquids - These are the substances where forces between the particles are weak enough to allow their movement. They don't have a specific shape but they have specific volume.
3. Gases - These substances have very weak forces between their particles. This causes the constituent particles to move freely. They have neither fixed shape nor a definite volume. They tend to completely occupy the container in which they are placed.
The nature of matter is also determined by its composition. If the matter is composed of more than one type of particles then it is called as a mixture while if it consists of a single type of particles then it is known as a pure substance.
hope it will help you
physical substance in general, as distinct from mind and spirit; (in physics) that which occupies space and possesses rest mass, especially as distinct from energy.
