Because of this particles of liquids are loosely packed compared to solid. But the force of attraction between particles of solids is less strong than that of solid. Strong force of attraction keeps the particles of liquids packed together.
Hence, the great force of attraction and least space between particles of solids and lowest kinetic energy of particles keep the particles at fixed places. The lowest kinetic energy of particles does not able to move the particles of solids. This makes the space between particles of solids almost negligible.
The particles of solids have minimum kinetic energy.īecause of great force of attraction particles of solids are closely packed together.There are minimum spaces between the particles of solids.The force of attraction between the particles of solids is very strong.The force of attraction between particles.The physical states of matter depend upon three main factors: Gas can flow easily and hence are called fluid.Ĭause of different physical states of matters.Gas gets the shape and volume of container.For example - air, oxygen, hydrogen, nitrogen, carbon-dioxide, etc. Matters which have indefinite shape and volume are called gases. Liquid flows and hence is called fluid.Liquid has less density compare to solid.Liquid gets the shape of container in which it is kept.Since liquid can flow, it is also called fluid. For example - milk, water, petrol, kerosene, alcohol, oil, etc. Matters which have fixed volume but indefinite shape are called liquids. All metals are solid except mercury and gallium. For example - stone, wood, brick, ice, sugar, salt, coal, etc.
Matters which have fixed volume and shape are called solids.
