Air, oxygen, hydrogen, nitrogen, steam, etc.
Why Solids, Liquids and Gases have different properties:
According to the kinetic theory of matter, the particles of matter are in continuous motion and possess kinetic energy.
Some forces of attraction also exist between the particles of matter. These are called inter particle forces. The forces of attraction tend to hold the particles together and control their movements.
The following properties of particles decide whether a given substance will exist as a solid, a liquid or a gas:
The spaces between the particles: the spaces between the particles are the minimum in solids, a little more in liquids, and the maximum in gases.
The force of attraction between particles: the forces of attraction between the particles are the strongest in solids, less strong in liquids and negligible in gases.
The amount of movement of particles (or kinetic energy of particles): the movement of particles is the minimum in solids, more in liquids and the maximum in gases.

Plasma and Bose- Einstein Condensate:
Plasma and Bose- Einstein Condensate are two more states of mater apart from three other discusse dpreviously.
Scientists now say that there are actually five states of matter: Solid, Liquid, Gas, Plasma and Bose- Einstein Condensate.
Plasma
Plasma is a mixture of free electrons and ions. Plasma occurs naturally in the stars (including the sun).
Inside the stars, the temperature is so high that the atoms break up. Some of the electrons break away from the atoms converting the rest of atoms into electrically charged particles called ions. This mixture of free electrons and ions in a star is called plasma.
The sun and other stars glow because of the presence of plasma in them.
Plasma can also be made on the earth by passing electricity through gases at very low pressure taking in a glass tube. The fluorescent tubes and neon sign bulbs form plasma when they are switched on.
Bose- Einstein Condensate
In 1920 Indian physicist Satyendra Nath Bose had done some calculations for a fifth state of matter. Building on it calculations, Albert Einstein predicted a new state of matter- the Bose Einstein Condensate (BEC).
The BEC is formed by cooling a gas of extremely low density (about one –hundred- thousandth the density of normal air) to super low temperature.
