away, but to get the smell from
cold food you have to go close.
3. A diver is able to cut through
water in a swimming pool. Which
property of matter does this
observation show?
4. What are the characteristicòs of
the particles of matter?​

Answer 1

Explanation:

1.The smell of hot sizzling food reaches several meter away because the particle of hot food have more kinetic energy and hence the rate of diffusion is more than the particle of cold food.

2.A diver is able to cut through water in a swimming pool because this shows that the particle of water has more intermolecular space and less force of attraction between their particles.

3. particles of matter have following characteristics :-

• they have intermolecular space .
• they have intermolecular force.
• particles of matter moves continuously.
