Explain characteristics of particle with example or activity?
Answers
THE IMPORTANT CHARACTERISTICS OF MATTER ARE:
•Particles of matter are very tiny in size.
•They have spaces between them.
•They are attracted towards each other.
1. Particles of matter are very tiny in size;
1. Particles of matter are very tiny in size;EXAMPLE:
(i) Take 2-3 crystals of copper sulphate and dissolve in 100 ml of water.(ii) Take out approximate 10 ml of this solution and put it into 90 ml of clear water.(iii) Take out 10 ml of this solution and put it into another 90 ml of clear water.
(i) Take 2-3 crystals of copper sulphate and dissolve in 100 ml of water.(ii) Take out approximate 10 ml of this solution and put it into 90 ml of clear water.(iii) Take out 10 ml of this solution and put it into another 90 ml of clear water.(iv) Keep diluting for 5-8 times.
(i) Take 2-3 crystals of copper sulphate and dissolve in 100 ml of water.(ii) Take out approximate 10 ml of this solution and put it into 90 ml of clear water.(iii) Take out 10 ml of this solution and put it into another 90 ml of clear water.(iv) Keep diluting for 5-8 times.Inference : A crystal of copper sulphate contains millions of tiny particles which keeps on dividing into smaller and smaller numbers with each dilution.
2. They have spaces between them;
EXAMPLE:
When sugar is added to the water, the sugar the particles adjust themselves in the space between the water particles. Hence, we can say that particles of matter have space between them.
3. They are attracted towards each other;
EXAMPLE;
observed that you find it easy to break a chalk, little tougher to break rubber band and toughest to break a coin. Conclusion: Particles of matter attract each other.
