- How are material grouped
- What is shorting?
- Grouping on the basis of similarity and differences
- Advantage of classification
Object Around Us
- Objects are made up of one or more materials.
- One material can be used to make different type of objects.
- It may be man-made or naturally occurring.
- Material is a substance which is used to make different objects.
Properties of materials
- Material occupy space.
- Materials have mass.
Material can be classified on the basis of physical state as:
(i) Solid
Examples: sand, steel and stone.
(ii) Liquid
Examples: oil, water and milk.
(iii) Gas
Examples: steam, nitrogen and oxygen.
General properties of material
Appearance
- Lustrous (all metals are lustrous, some are more and some are less).
- Non-lustrous (wood, rubber and piece of rock)
Hardness (Hard and soft)
- Brittle (break into small pieces or become powdered when hammered. Eg: - glass and salt)
- Malleable (spread into sheets when beaten. Metal are malleable
- Ductile ( which can draw into thin and long wire)
Visibility
- Transparent (Materials that allow the entire light pass through it, like glass, water etc.)
- Translucent (Materials that allow some light to pass through it, like coloured glass, oiled paper.)
- Opaque (The material which do not allow light to pass through it, like stone, wood etc.)
Electricity
- Good conductor (Metals are good conductor ; electricity can pass through it)
- Bad conductor (non-metals ; electricity can’t pass through it) Heat
- Good conductor (metals are good conductor)
- Bad conductor (non-metals are bad conductor)
Materials may float and can sink in water
- Material which sinks in water is denser than water
- Material which floats on water is less dense than water.
Solubility of a substance in water
- The substance like salt and sugar which disappear in water are called as soluble.
- The substances which don’t disappear in water are known as insoluble in water.
Miscible and immiscible liquid
- When two liquid mixed and they do not mixed well is known as immiscible.
- The liquids which mix well with water are said to be miscible.
Solute, solvent and solution?
- The substances which dissolve in water are called solute.
- A solvent is a substance that dissolves the solute to make the solution.
- The mixture of solute and solvent is called solution.
How are material grouped
The materials which are similar in one or two ways can be put in one group.
- Things made from wood.
- Things made from fibre.
- Things made from metal.
- Things made from ceramic.
- Things made from glass.
- Things made from plastic.
- Things made from rubber.
- Things that are liquids such as oil.
Advantages of classification
- Helps in identifications of objects.
- Helps in sorting of objects.
- Helps in locating things.
- Makes study of different objects easy and more meaningful rather than studying each other separately.
- Helps to understand similarities and dissimilarities among objects.
Ans. Classification of materials into various groups on the basis of similarities and dissimilarities in properties is known as sorting of materials.
2. What is the need to classify materials?
Ans. Classification of materials is done to make the study of objects easier. Also, classification makes it easier to locate objects.
3. How are hard materials different from soft materials? Give two examples of each.
Ans. Hard materials: Those materials which cannot be easily scratched or compressed are called hard materials.
Example: Wood, stone, glass etc.
Soft materials: Those materials which can be easily scratched or compressed are called soft materials. Example: wool, foam, butter etc.
4. Classify the following materials on the basis of their solubility in water:
Material Solubility in water
Milk Soluble
Alcohol Soluble
Sand Insoluble
Copper sulphate Soluble
Wax Insoluble
Chalk powder Insoluble
5. What is the importance of oxygen dissolved in water?
Ans. Oxygen gas dissolved in water is used by the aquatic plants and animals for respiration.
6. Why does water play an important role in the functioning of our body?
Ans. Water plays an important role in the functioning of our body as it can dissolve a large number of substances in it.
7. Name any two liquids which are miscible with water and two which are insoluble in water.
Ans. Liquids miscible with water: Vinegar, lemon juice
Liquids immiscible with water: petrol, groundnut oil
8. Give one word for the following:
a) Shine observed on the surface of metal.
b) Substances through which light cannot pass.
c) Substances which do not dissolve in other substance.
9. Name two materials which float on water and two which sink in water.
Ans.
Materials which float on water: Dry leaves, oil
Materials which sink in water: stone, chalk
10. How are transparent objects different from translucent objects?
Ans. Transparent materials: The materials through which we can see clearly are known as transparent materials. Example: glass, air etc.
Translucent materials: The materials through which we cannot see clearly are known as translucent materials. Example: butter paper, ground glass, frosted glass etc.
11. Name two gases which dissolve in water to some extent.
Ans. Oxygen, carbon dioxide
12.Fill in the blanks:
a) A feather ___________ on the surface of water.
b) ________________ cannot be compressed easily.
c) Coconut oil ____________ on the surface of water.
d) Common salt is ____________ in water.
e) Materials usually lose _____________ and appear dull if kept exposed to air and moisture for a long time.
f) Water contains ___________ oxygen that supports life under water.
13. State one property of metals which is used for making jewellery.
Ans. Lusture
14. State true or false:
a) Bark of tree is rough.
Ans. True
b) Wood is a transparent material.
Ans. False
c) Carbon dioxide is insoluble in water.
Ans. False
d) Coconut oil is immiscible in water.
Ans. True
15. Find the odd one out from the following :
Aluminium, iron, copper, silver, sand
Ans. Sand as it is not lusturous.
