Matter can be classified into three categories depending upon its physical state namely solid, liquid and gaseous states. Solids have a definite volume and shape; liquids also have a definite volume but no definite shape; gases have neither a definite volume nor a definite shape.

Kinetic Theory of Matter
Matter is made up of particles which
are in continual random motion.

SOLIDS
•Particles of solids are
tightly packed, vibrating
about a fixed position.
•Solids have a definite

LIQUID
Particles of liquids are
tightly packed, but are
far enough apart to
slide over one
