Question

Physical nature of matter

Answer 1

1.matter is made up of particles. 2.the particles of matter very very small. 3. The particles of matter are very large in number

Answer 2

Answer:

1. matter is made up of particle

• every matter is composed of similar repeating units called a particles.
• the nature of particles and physical forces among them be determine the nature of the matter
• every particle of matter is bonded to other particles due to the attractive forces among them
• every particle of matter has its own energy to move
• for example, when we dissolve salt in water the particles of salt get into the spaces between particles of water

2. particles of matter have spaces between them

• every matter of different states is formed by the union of a number of constituting particles which processes interstitial spaces between them
• this space may vary in different matters because of the different arrangements and the nature of particles
• the space between two neighbouring particle units is known as Interstitle space

3. particles of matter move continuously

• if you put a drop of ink into water and keep it undisturbed for sometime, you will find later on that ink has spread throughout the water
• this is because the particles of INk keep moving
• so particles of matter move continuously
• their movement depends upon the nature of matter, the physical forces operating between them and the kinetic energy of particles

4. particles of matter attract each other

• all the material looks United and constituted because there constituting particles are assembled
• a question arises that why particles assemble together? the answer is attractive force.
• every particle of matter exerts and attractive force on its neighbouring particles and hence they are assembled together
• efficiency of this forces very for the different type of materials.
• this forces also predict the size and the shape of the material

5. particles of matter are very small

• if you put a drop of blue ink into 500 ml water, the colour of water will turn blue
• again take a drop of the solution and put it in another 500ml water
• again the water will turn blue however the blue colour fades
• this shows that a drop of ink contains millions of particle which in turn shows that the particles of matter are very small.
