what are the charecteristic of particles of matter?
Answers
every substance is made up of particles. These particles exhibit some characteristics. They can influence the state and properties (physical and chemical) of a substance. The three characteristics shown by particles of matter are as follows.
Particles Have Space Between Them
There are small voids between every particle in a matter. This characteristic is the concept behind the solubility of a substance in other substances. Let’s try to understand this with an illustration.
Take a glass of water. Put a teaspoon of salt/sugar and mix them properly. You will observe that the water is still clear. This is because the particles of salt/sugar get into the interparticle spaces between the water particles. This proves that there are voids between particles of a substance. If you add more salt/sugar, it will dissolve until all the space between water particles get filled.
Particles Are Constantly in Motion (or) Particles are Continuously Moving
Particles of the matter show continuous random movements. The kinetic energy they possess helps them in this movement. The spreading of ink in a beaker of glass, the smell that comes from agarbattis, etc. are few illustrations that show the movement of particles of a substance. When the particles of two different types of matters intermix on their own, the phenomenon is called diffusion.

Characteristics of Particles of Matter
Diffusion of particles becomes fast when the temperature is increased. A rise in temperature increases the kinetic energy of the particles, making them move more vigorously.
Particles Attract Each Other
Take an iron rod, a stick of chalk, and a pen. Try to break each one of these. Which one of these is easy to break? The iron rod is stronger than the other two items. What makes an item stronger? Yes, it’s the particles in them which are held by the inter-particle force of attraction.
In every substance, there is an inter-particle force of attraction acting between its particles. To break something we need to overcome this force. The strength of the force differs from one substance to another.
The inter-particle force of attraction and the kinetic energy of the particles primarily determine the physical state of any matter.
Explanation:
The characteristics of particles of matter are:
All matter is composed of very small particles which can exist independently.
Particles of matter have spaces between them.
Particles of matter are continuously moving.
Particles of matter attract each other.
