Matter in our surrounding
Matter
Physical state Chemical state
Solid Pure Mixture
Liquid element compound homogenous heterogeneous
Gas
Pure substance
When all the constituents particles of a substance are chemically similar to
each other celled as pure substance.
Matter :Any object which has mass and occupies space called matter.
E.g. book, pen, table, etc.
Characteristics of particles
1. Particles of matter are always in motion.
2. There are spaces between particles of matter.
3. Matter exists in different state (solid, liquid, gas)with varying properties due
to arrangements and movement of particles.
4. These properties like color, boiling point, melting point can be observed
without changing the substance composition.
5. Particles of mater attract each other due to inter molecular force.
Physical division of matter
There are three division 1matter are : solid, liquid, gas.
1.solid
Solid have different volume and shape.
The force between solid particles are strong.
E.g. ice, wood, metal.
Particles are held very close to each other in solid.
Liquid - in liquid, the particles are close to each other but they can move around.
