Tips and Tricks on Matter In Our Surroundings


 


1
Following properties of particles decide the state of matter
1.Intermolecular distance
2.Force of attraction between the particles
3.Kinetic energy of the particles



2
In case of solids, the intermolecular spaces are very small and intermolecular forces are very large. The molecules can vibrate about their mean position, but can not change their positions. Hence the solids have definite shape, definite volume and are incompressible.

For every gas there is a certain temperature above which the gas can not be liquefied however large be the pressure applied. The temperature above which a gas not be liquefied is called critical temperature and the corresponding pressure is called critical pressure
