Question

Which characteristics property of particles is illustrate here

Answer 1

Answer:

These are the four main characteristics of particles of matter  

Particles of matter are very tiny in size: When a teaspoon of salt is dissolved in one or two litres of water, every drop of that water taste salty. When few drops of Dettol are mixed in water, whole water gives the smell of Dettol. Even after diluting this dettol mixed water, it gives the smell of dettol. This proves that particles of matter are very small.  

They have space between them: We can move our hand through the air easily. To move our hand in liquid, such as water, we have to apply some force, but for a solid such as wood, we cannot move our hand. This is because  the force of attraction between particles of gas is almost negligible, in liquid the forces of attraction is moderate but it is greatest in  solid.  

Particles of matter move constantly: Example: Diffusion and Brownian motion give the evidence that particles are in motion.

They are attracted towards each other: For example, breaking a chalk is easier than breaking a nail. This proves that attraction varies from particles of one substance to another. Cohesion means the force of attraction between the particulate matter of the same substance.

have a good day.
