All About Matter
Introduction
Anything which occupies space and has mass is called
matter. If we look around us, we can see a large no
of things of different shapes, sizes and textures.
Many of these things are used by us in our everyday
life. For Example, we eat food, drink water, breathe
in air and wear clothes. We use table and chair for
studying and bed for sleeping. We also see other
human beings, various plants and trees around us.
The things like food, water, air, clothes, table, chair,
human beings, animals, plants, and trees etc., are all
examples of matter
Matter In Our Surroundings
Everything in this universe is made up of material
which scientists have named “matter”. The air we
breathe, the food we eat, stones, clouds, stars, plants
and animals, even a small drop of water or a particle
of sand– each thing is matter.
Early Indian philosophers classified matter in the
form of five basic elements –air, earth, fire, sky and
water.
Modern day scientists have evolved two types of
classification of matter based on their physical
properties and chemical nature.
Classification of matter
Nowadays scientists have classified matter in the
following two types:-
The physical classification based on physical
properties of matter.
The chemical classification chemical composition of
matter.
Matter can be Classified
On the basis of the physical state matter is classified
as solids, liquids and gases.
On the basis of chemical composition matter is
classified as pure substances and mixtures.
• Pure substances may be elements or compounds.
• Mixtures may be homogeneous mixtures or
heterogeneous mixtures.
Physical Nature Of Matter
Matter is made up of particles.
The particles of matter are very tiny.
The particles of matter have space between them.
The particles of matter are continuously moving.
The particles of matter attract each other.
1. Matter is made up particles :-
Activity :- Take some water in a beaker and note its
level. Dissolve some salt or sugar in it with the help
of a glass rod. The salt dissolves in the water but the
level of water does not change. This is because the
particles of water get into the space between the
particles of water. This shows that matter is made up
of particles.
2.The particles of matter are very
tiny
Activity :- Dissolve 2 – 3 crystals of potassium
permanganate in 100ml of water in a beaker. Take
10ml of this solution and dissolve in 100ml of water.
Take 10ml of this solution and dissolve in 100ml of
water. Repeat this process 5 – 6 times. This shows
that a few crystals of potassium permanganate can
color a large volume of water because there are
millions of tiny particles in each crystal.
3. The particles of matter have
space between them
Activity :- Take some water in a beaker and note its
level. Dissolve some salt or sugar in it with the help
of a glass rod. The salt dissolves in the water but the
level of water does not change. This is because the
particles of salt get into the space between the
particles of water.
4. Particles of matter are
continuously moving
Activity :- Take some water in a beaker and put a drop
of blue or red ink slowly along the sides of the
beaker. Leave it undisturbed for a few hours. The ink
spreads evenly throughout the water due to the
movement of the particles of water and ink.
The intermixing of two or more different types of
matter on their own is called diffusion.
5. Particles of matter attract each
other :-
Activity :- Take an iron nail, a piece of chalk and a
rubber band. Try breaking them by hammering,
cutting or stretching. It is more easier to break the
chalk, less easier to break the rubber band and
difficult to break the iron nail. This is because the
particles in the iron nail are held together with
greater force than in the rubber band or chalk.
States Of Matter
Matter exists in three different states. They
are :-
Solid
Liquid
Gas
A. Properties of solids :-
Solids have definite shapes and fixed volume.
The space between the particle is minimum.
The force of attraction between the particles is
maximum.
The movement of the particles is minimum.
They are least compressible.
Their rate of diffusion is least.
B. Properties Of Liquid
Liquids have no definite shape but have fixed
volume. Liquids take the shape of the container.
The space between the particles is intermediate.
The force of attraction between the particles is
intermediate.
The movement of the particles is intermediate.
They are less compressible.
Their rate of diffusion is more than solids.
C. Properties Of Gases
Gases have no definite shape or fixed volume. Gases
occupy the whole space of the container.
The space between the particles is maximum.
The force of attraction between the particles is
minimum.
The movement of the particles is maximum.
They are most compressible.
Their rate of diffusion is more than solids and
liquids.
Change Of State Of Matter
When a solid is heated it changes into liquid. When a
liquid is heated it changes into gas.
When a gas is cooled it changes to liquid. When a
liquid is cooled it changes into solid.
E.g.:- If ice is heated it changes into water. If water is
heated it changes into steam. If steam is cooled it
changes into water. If water is cooled it changes into
ice.
A. Melting Or Fusion
When a solid is heated, the particles begin to vibrate with
greater speed and begin to move more freely. Then at a
particular temperature the solid melts and changes into
liquid. The process of melting is also known as fusion.
The temperature at which a solid melts is called its melting
point. The melting point of ice is 00C or 273 K.
Latent Heat Of Fusion:-The amount of heat energy required to
change 1kg of a solid into liquid at atmospheric pressure at its
melting point is called the latent heat of fusion.
B. Boiling
When a liquid is heated, its particles begin to move even faster. Then at a
particular temperature the liquid begins to boil and changes into gas
(vapour).
Boiling is a bulk phenomenon. When a liquid boils the bulk of the liquid
changes into vapour.
The temperature at which a liquid starts boiling is called its boiling point.
The boiling point of water is 1000C or 373K ( 273 + 100).
Latent heat of vaporization :-
The amount of heat energy required to change 1kg of a liquid into gas at
atmospheric pressure at its boiling point is called the latent heat of
vaporization.
C. Sublimation
The change of state directly from solid to gas or from
gas to solid is called sublimation.
E.g. :- If solid camphor or ammonium chloride is
heated, it changes into vapour. If the vapours are
cooled it changes into solid.
D. Effect of pressure on gases
When pressure is applied on gas the particles come
closer and the gas changes into liquid.
We can liquefy gases by applying pressure and
reducing the temperature.
Compressed solid carbon dioxide is called dry ice. If
the pressure is reduced it changes directly to gas
without coming into liquid state. So solid carbon
dioxide is known as dry ice.
Evaporation
The change of a liquid into vapour at any
temperature below its boiling point is called
evaporation.
Evaporation is a surface phenomenon. Particles
from the surface gain enough energy to overcome
the forces of attraction and changes to vapour state.
Factors affecting evaporation
The rate of evaporation depends upon surface area,
temperature,
humidity and wind speed.
Increase in the surface area increases the rate of
evaporation.
Increase in temperature increases the rate of
evaporation.
Increase in humidity decreases the rate of
evaporation.
Increase in wind speed increases the rate of
evaporation.
Cooling Effect Of Evaporation
When a liquid evaporates, the particles of the liquid absorb
heat from the surroundings and evaporates. So the
surroundings become cold.
E.g. :- People sprinkle water on the roof or open ground
because during evaporation water absorbs heat makes the
hot surface cool.
During summer we sweat more because during
evaporation the sweat absorbs heat from our body making
the body cool.
Wearing cotton clothes in summer keeps us cool because
cotton absorbs sweat and when the sweat evaporates it
absorbs heat from our body making the body cool.

Matter in our surroundings

  • 4. Introduction Anything which occupies space and has mass is called matter. If we look around us, we can see a large no of things of different shapes, sizes and textures. Many of these things are used by us in our everyday life. For Example, we eat food, drink water, breathe in air and wear clothes. We use table and chair for studying and bed for sleeping. We also see other human beings, various plants and trees around us. The things like food, water, air, clothes, table, chair, human beings, animals, plants, and trees etc., are all examples of matter
  • 5. Matter In Our Surroundings Everything in this universe is made up of material which scientists have named “matter”. The air we breathe, the food we eat, stones, clouds, stars, plants and animals, even a small drop of water or a particle of sand– each thing is matter. Early Indian philosophers classified matter in the form of five basic elements –air, earth, fire, sky and water. Modern day scientists have evolved two types of classification of matter based on their physical properties and chemical nature.
  • 6. Classification of matter Nowadays scientists have classified matter in the following two types:- The physical classification based on physical properties of matter. The chemical classification chemical composition of matter.
  • 7. Matter can be Classified On the basis of the physical state matter is classified as solids, liquids and gases. On the basis of chemical composition matter is classified as pure substances and mixtures. • Pure substances may be elements or compounds. • Mixtures may be homogeneous mixtures or heterogeneous mixtures.
  • 8. Physical Nature Of Matter Matter is made up of particles. The particles of matter are very tiny. The particles of matter have space between them. The particles of matter are continuously moving. The particles of matter attract each other.
  • 9. 1. Matter is made up particles :- Activity :- Take some water in a beaker and note its level. Dissolve some salt or sugar in it with the help of a glass rod. The salt dissolves in the water but the level of water does not change. This is because the particles of water get into the space between the particles of water. This shows that matter is made up of particles.
  • 10. 2.The particles of matter are very tiny Activity :- Dissolve 2 – 3 crystals of potassium permanganate in 100ml of water in a beaker. Take 10ml of this solution and dissolve in 100ml of water. Take 10ml of this solution and dissolve in 100ml of water. Repeat this process 5 – 6 times. This shows that a few crystals of potassium permanganate can color a large volume of water because there are millions of tiny particles in each crystal.
  • 11. 3. The particles of matter have space between them Activity :- Take some water in a beaker and note its level. Dissolve some salt or sugar in it with the help of a glass rod. The salt dissolves in the water but the level of water does not change. This is because the particles of salt get into the space between the particles of water.
  • 12. 4. Particles of matter are continuously moving Activity :- Take some water in a beaker and put a drop of blue or red ink slowly along the sides of the beaker. Leave it undisturbed for a few hours. The ink spreads evenly throughout the water due to the movement of the particles of water and ink. The intermixing of two or more different types of matter on their own is called diffusion.
  • 13. 5. Particles of matter attract each other :- Activity :- Take an iron nail, a piece of chalk and a rubber band. Try breaking them by hammering, cutting or stretching. It is more easier to break the chalk, less easier to break the rubber band and difficult to break the iron nail. This is because the particles in the iron nail are held together with greater force than in the rubber band or chalk.
  • 14. States Of Matter Matter exists in three different states. They are :- Solid Liquid Gas
  • 15. A. Properties of solids :- Solids have definite shapes and fixed volume. The space between the particle is minimum. The force of attraction between the particles is maximum. The movement of the particles is minimum. They are least compressible. Their rate of diffusion is least.
  • 16. B. Properties Of Liquid Liquids have no definite shape but have fixed volume. Liquids take the shape of the container. The space between the particles is intermediate. The force of attraction between the particles is intermediate. The movement of the particles is intermediate. They are less compressible. Their rate of diffusion is more than solids.
  • 17. C. Properties Of Gases Gases have no definite shape or fixed volume. Gases occupy the whole space of the container. The space between the particles is maximum. The force of attraction between the particles is minimum. The movement of the particles is maximum. They are most compressible. Their rate of diffusion is more than solids and liquids.
  • 18.
  • 19. Change Of State Of Matter When a solid is heated it changes into liquid. When a liquid is heated it changes into gas. When a gas is cooled it changes to liquid. When a liquid is cooled it changes into solid. E.g.:- If ice is heated it changes into water. If water is heated it changes into steam. If steam is cooled it changes into water. If water is cooled it changes into ice.
  • 20.
  • 21. A. Melting Or Fusion When a solid is heated, the particles begin to vibrate with greater speed and begin to move more freely. Then at a particular temperature the solid melts and changes into liquid. The process of melting is also known as fusion. The temperature at which a solid melts is called its melting point. The melting point of ice is 00C or 273 K. Latent Heat Of Fusion:-The amount of heat energy required to change 1kg of a solid into liquid at atmospheric pressure at its melting point is called the latent heat of fusion.
  • 22. B. Boiling When a liquid is heated, its particles begin to move even faster. Then at a particular temperature the liquid begins to boil and changes into gas (vapour). Boiling is a bulk phenomenon. When a liquid boils the bulk of the liquid changes into vapour. The temperature at which a liquid starts boiling is called its boiling point. The boiling point of water is 1000C or 373K ( 273 + 100). Latent heat of vaporization :- The amount of heat energy required to change 1kg of a liquid into gas at atmospheric pressure at its boiling point is called the latent heat of vaporization.
  • 23.
  • 24. C. Sublimation The change of state directly from solid to gas or from gas to solid is called sublimation. E.g. :- If solid camphor or ammonium chloride is heated, it changes into vapour. If the vapours are cooled it changes into solid.
  • 25. D. Effect of pressure on gases When pressure is applied on gas the particles come closer and the gas changes into liquid. We can liquefy gases by applying pressure and reducing the temperature. Compressed solid carbon dioxide is called dry ice. If the pressure is reduced it changes directly to gas without coming into liquid state. So solid carbon dioxide is known as dry ice.
  • 26.
  • 27. Evaporation The change of a liquid into vapour at any temperature below its boiling point is called evaporation. Evaporation is a surface phenomenon. Particles from the surface gain enough energy to overcome the forces of attraction and changes to vapour state.
  • 28. Factors affecting evaporation The rate of evaporation depends upon surface area, temperature, humidity and wind speed. Increase in the surface area increases the rate of evaporation. Increase in temperature increases the rate of evaporation. Increase in humidity decreases the rate of evaporation. Increase in wind speed increases the rate of evaporation.
  • 29. Cooling Effect Of Evaporation When a liquid evaporates, the particles of the liquid absorb heat from the surroundings and evaporates. So the surroundings become cold. E.g. :- People sprinkle water on the roof or open ground because during evaporation water absorbs heat makes the hot surface cool. During summer we sweat more because during evaporation the sweat absorbs heat from our body making the body cool. Wearing cotton clothes in summer keeps us cool because cotton absorbs sweat and when the sweat evaporates it absorbs heat from our body making the body cool.
