(b) Materials can be grouped based on their common properties.
Answer: True.
Explanation: Materials are classified according to properties such as hardness, lustre, transparency and solubility.
(c) Glass is an opaque material.

(d) Sugar dissolves in water.
Answer: True.
Explanation: Sugar is a soluble substance.
(e) Sand is soluble in water.
Answer: False.
Explanation: Sand does not dissolve in water.
Question 2.
What is meant by classification of materials?
Answer:
Classification of materials is the process of arranging materials into different groups based on their similar properties such as colour, hardness, lustre, transparency or solubility. Classification helps us study and identify materials easily.
Question 3.
Why are different materials used for making different objects?
Answer:
Different materials have different properties. Objects are made from materials that are best suited for their purpose. For example, cooking utensils are made of metal because metals conduct heat, while raincoats are made of waterproof materials.
Question 4.
Differentiate between lustrous and non-lustrous materials.
Answer:
| Lustrous Materials | Non-Lustrous Materials |
|---|---|
| Have a shiny surface. | Do not have a shiny surface. |
| Usually metals. | Usually non-metals. |
| Examples: Iron, Copper, Aluminium. | Examples: Wood, Paper, Rubber. |
Question 5.
Differentiate between hard and soft materials.
Answer:
| Hard Materials | Soft Materials |
|---|---|
| Difficult to scratch or compress. | Easy to scratch or compress. |
| Strong and rigid. | Flexible or compressible. |
| Examples: Stone, Iron. | Examples: Sponge, Rubber. |

Question 7.
What are soluble and insoluble substances?
Answer:
Substances that dissolve completely in water are called soluble substances, such as sugar and salt. Substances that do not dissolve in water are called insoluble substances, such as sand, chalk powder and sawdust.
Question 8.
What is matter?
Answer:
Anything that has mass and occupies space is called matter. Air, water, wood, stone, metals and plastic are all examples of matter.
Question 9.
What is mass?
Answer:
Mass is the quantity of matter present in an object. It tells us how heavy or light an object is. Its SI unit is kilogram (kg).
Question 10.
What is volume?
Answer:
Volume is the space occupied by a substance or an object. Liquids are generally measured in litres (L) and millilitres (mL).
Activity-Based Answers
• Why can't a tumbler made of cloth hold water?
Answer: Cloth absorbs water and allows it to pass through its pores. Therefore, it cannot hold water.
• Why are different balls made from different materials?
Answer: Different sports require different properties such as hardness, elasticity, weight and bounce. Hence, different materials are used.
• Why are metals generally used for cooking utensils?
Answer: Metals conduct heat efficiently and are strong enough to withstand high temperatures.
• Why is oxygen dissolved in water important?
Answer: Dissolved oxygen helps aquatic animals and plants survive in water.
• Why is classification of materials useful?
Answer: Classification makes it easier to identify, compare and study materials based on their properties and uses.
