Weekly Quiz Competition

Question 1
1 / -0

Select a pair of solute and solvent materials to form solution:

A
Chalk powder and water

B
Alcohol and water

C
Milk and oil

D
Glass and water

Solution

In general, organic compounds are insoluble in water. Though alcohol is an organic compound it is soluble in water due to hydrogen bonding.
Question 2
1 / -0

Select the material which is insoluble in water.

A
Sugar

B
Salt

C
Chalk powder

D
Oxygen gas

Solution

Some substances like salt and sugar completely disappear when mixed with water. Thus, they are soluble in water.
Other substances like chalk powder do not mix with water or disappear. They are insoluble in water.
Some gases like oxygen also dissolve in water (soluble). This dissolved oxygen is important for the survival of many aquatic animals.
Question 3
1 / -0

Identify the material(s) with which plates are made.

A
Glass

B
Plastic

C
Metal

D
All of above

Solution

Plates are generally made from steel (which is a metal). They are also made from plastics and glass.
Question 4
1 / -0

Which of the following object can be made by same materials?

A
bottles, utensils, toys

B
chair, table, water bottles

C
ornaments, umbrella, tents

D
well, tube well, handpump

Solution

A plastic is any material that can be shaped or molten into any form, so we can find it in bottles, utensils, toys, etc.

Chairs and tables are generally made up of wood but not bottles as water can damage the wood.

Ornaments are made up of shiny metals like gold and silver, whereas umbrellas and tents are not made out of metals like gold and silver.

Wells are made up of bricks whereas tube wells and handpumps are not made up of bricks.

Hence, option $$A$$ is the correct answer.
Question 5
1 / -0

Which of the following object(s) are made from plastic?

A
Bucket

B
Table

C
Plate (thali)

D
All of the above

Solution

Plastic is a very useful polymer. It is used on a large scale for the production of various articles. Buckets, tables, plates, chairs, bottles are few examples of articles made of plastic.

Hence answer is option $$D$$.
Question 6
1 / -0

Find odd one out on the basis of the solubility of the material.

A
Sugar

B
Salt

C
Chalk

D
Wood

Solution

Wood is not at all soluble in water whereas sugar and salt are soluble and chalk $$(CaCO_3)$$ is slightly soluble in water.
Question 7
1 / -0

Take 2 glasses $$A $$ and $$B$$ and put tap water in $$A$$ and salt water in $$B$$. Now add 1 egg in each. In which of the glass, an egg will sink?

A
$$A$$

B
$$B$$

C
Both

D
None of them

Solution

Salt water is denser than fresh water. So, if we put egg in salt water the egg floats and if we put egg in tap water the egg will sink.
Question 8
1 / -0

Which of the following material(s) is/are used to make plate (thali)?

A
steel

B
glass

C
plastics

D
All of the above

Solution

Plates that are used frequently are made of steel or glass whereas disposable plates are made of plastics.

Hence, the answer is option D.

I: Salt, sugar, flour
II: Copper, gold, silver
III: Petrol, kerosene, paper

Identify the property common to each group.

A
I- Solid, II- Bad conductors of heat, III- Liquid

B
I- Edible, II-non-metallic, III- Non-inflammable

C
I- Edible, II- Metallic, III- Inflammable

D
I- Solid, II-Good conductors of heat, III- Non-inflammable

Solution

Salt, sugar, flour - Edible

Copper, gold, silver - Metallic

Petrol, kerosene, paper - Inflammable.

Hence the correct option is C.
Question 10
1 / -0

Which of the following object(s) can be made from steel?

A
Cupboard

B
Table

C
Chair

D
All of the above

Solution

Steel is an important material that is used on a very large scale in modern industry due to its high durability and strength. It is also used to manufacture steel tables, chairs, cupboards, fans, utensils, etc. Thus answer is option D.
