Answer 2

HEY!

1. chair, near, Almonds, smell of perfume and cold drink are all matter. this is because all of these occupy some space and have mass. In solid state ,chair and Almonds are matter .Cold drink is matter in liquid state. An Air and smell of perfume are matter in gaseous state .
2. The smell of hot sizzling food reaches you several metres away, but to get the smell from cold food you have to go close because the kinetic energy of the particles of matter increases with the increase in temperature.
3. The driver is able to cut through water in a swimming pool. this observation shows that the matter has spaces between them so that the particles can move from one place to another to accommodate the body of the driver for stop.
4. The particles of matter are very, very small. The particles of matter have spaces between them. The particles of matter are continuously moving. The particles of matter attract each other.

I hope this solution will help you
