Case Study Questions on The World of Metals and Non-metals

Case Study Question 1:

Passage: A Visit to the Ironsmith

Yashwant and Anandi visited a local ironsmith in Rajasthan for a school project. They observed Sudarshan uncle heating iron blocks and beating them into tools like axes and tongs. Anandi was fascinated to see iron being flattened and learned that metals have specific properties such as malleability, ductility, and lustre. Their teacher later asked them to perform experiments using copper, aluminium, coal, sulfur, and wood to test for hardness, appearance, and malleability.

Q1. Which property allows a metal like iron to be flattened into sheets when beaten?
(a) Ductility
(b) Brittleness
(c) Malleability
(d) Elasticity
Answer: (c)
Difficulty Level: Easy
Explanation: Malleability is the property of metals that allows them to be beaten into thin sheets without breaking.

Q2. Which of the following materials is non-malleable and breaks when hammered?
(a) Aluminium
(b) Sulfur
(c) Copper
(d) Iron
Answer: (b)
Difficulty Level: Moderate
Explanation: Sulfur is a non-metal and brittle in nature; it breaks instead of flattening under force.

Q3. What characteristic do copper, aluminium, and iron have in common, according to the table activity?
(a) All are brittle
(b) All are lustrous and hard
(c) All are soft and dull
(d) All break when hammered
Answer: (b)
Difficulty Level: Moderate
Explanation: These metals are hard and have a shiny (lustrous) appearance, as confirmed through observation.

Q4. Why is wood neither considered malleable nor brittle?
(a) It changes color when hammered
(b) It flattens like metal
(c) It does not flatten or break on hammering
(d) It is a good conductor
Answer: (c)
Difficulty Level: Tough
Explanation: Wood neither flattens nor breaks when hammered, so it is considered neither malleable nor brittle.


Case Study Question 2:

Passage: Testing Metal Properties at Home

As part of their homework, the students tested various kitchen items to observe other properties of metals, such as ductility, sonority, heat conduction, and electrical conductivity. They dipped metal and wooden spoons into hot water and checked which spoon got hotter. They also dropped a metal coin and a wooden block to hear the sound. In another experiment, they used a tester circuit to see if the materials conducted electricity.

Q1. Why did the metal spoon become hotter than the wooden spoon in hot water?
(a) Metal reacts with hot water
(b) Metal is a poor conductor of heat
(c) Metal is a good conductor of heat
(d) Wooden spoons absorb water
Answer: (c)
Difficulty Level: Easy
Explanation: Metals allow heat to pass through them easily, which is why the metal spoon gets hot.

Q2. What property of metals allows them to produce a ringing sound when dropped?
(a) Malleability
(b) Conductivity
(c) Sonority
(d) Elasticity
Answer: (c)
Difficulty Level: Easy
Explanation: Sonority is the property of metals that enables them to produce a ringing sound.

Q3. Which of the following materials would cause a bulb to glow in a tester circuit?
(a) Plastic rod
(b) Iron nail
(c) Rubber band
(d) Nylon rope
Answer: (b)
Difficulty Level: Moderate
Explanation: Iron is a metal and a good conductor of electricity, so it completes the circuit.

Q4. Why is rubber used in the handles of tools used by electricians?
(a) It is shiny and attractive
(b) It is soft and comfortable
(c) It is a poor conductor of electricity
(d) It reacts with metals
Answer: (c)
Difficulty Level: Moderate
Explanation: Rubber is an insulator, so it prevents electric current from passing through, ensuring safety.

We hope the given case study questions for The World of Metals and Non-metals Class 7 helps you in your learning.
