Nature of Matter

Matter

Anything which has mass and occupies space is called matter.

The matter can exist in three physical States solid , liquid and gas.

1. Solid - solid particles are held very close to each other in an orderly fashion and there is not much freedom of movement. Solids have definite volume and definite shape.                                      
2. Liquid - liquid particles are close to each other but they can move around. Liquids have definite volume but not definite shape. Detect the shape of the container in which they are placed.                                                
3. Gasses - gases particles are far apart as compared to those present in solid or liquid states and their movement is easy and fast because of such arrangement of particles. Gases have neither definite volume nor definite shape day completely occupy the container in which they are placed.
