Answer:
Chair, air, love, smell, hate, almonds, thought, cold, cold drink, smell of perfume. Anything that occupies space and has mass is called matter. Matter can exist in three physical states that are Solid, Liquid, and Gaseous.
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.
The smell of hot sizzling food reaches to you several meters away but to take smell from cold food you have to go close because particles of hot sizzling food possess large kinetic energy and diffuse in air rapidly and reach several meters away whereas particles of cold food possess less kinetic energy and are not able
Property of matter observed
This shows that the particles of matter have spaces between them. The interparticle forces of attraction between liquid particles are not very strong hence the force applied by the diver is enough to overcome these forces of attraction.
Hope it helps you dear friend
