Introduction to distance between particles:
Particle is a minute quantity or fragment. It is a relatively small or the smallest discrete portion of amount of something. It is the basic unit of matter and energy such as a molecule, atom, proton, electron, or photon.
According to Kinetic molecular Theory,
- All matter is composed of tiny particles.
- These tiny particles of matter are in constant motion.
- Solids, liquids and gases differ in the freedom of motion of their particles and the extent to which the particles interact.
- The amount of motion is proportional to temperature. The particles move faster with the increase in temperature.
Nature and Distance between Particles in Solids, Liquids and Gases:Back to Top
Solids, liquids and gases are the three main states of matter. The nature and distance between particles differs in Solids, Liquids and Gases as given below:
- Solid particles of are tightly packed,
- Solid particles vibrate about a fixed position,
- Solids have a definite shape and a definite volume,
- Solids cannot be easily compressed because of very less free space between particles and
- Solids do not flow because the particles cannot move or slide over one another.
- Liquids have a definite volume, but do not have a definite shape since because of less tightly packed liquid particles as compared with solids,
- Liquid particles are far enough apart to slide over one another and therefore, liquids flow easily and
- Liquids cannot compress easily since there is less free space between particles as compared with gases.
- Particles of gases are much far apart and move freely and therefore, gases do not have a definite shape or a definite volume,
- Because of more free space between particles, gases can be easily compressed and
- Because of the random and faster movement of the particles as compared with solids or liquids, Gases can flow very easily.
The distance between the particles in different states of matter such as solids, liquids and gases are as shown in the figure below:
