After addition of salt in the water- a)boiling point increases
- b)boiling point decreases
- c)no effect on boiling point
- d)freezing point increases
Correct answer is option 'A'. Can you explain this answer?
a)
boiling point increases
b)
boiling point decreases
c)
no effect on boiling point
d)
freezing point increases
| | Skyhigh Academy answered |
Salt raises the boiling point of water by increasing its boiling temperature. This happens because dissolved salt makes it harder for water molecules to escape as vapour. Therefore, boiling point increases.
What we can do to make water potable?- a)boiling

- d)at 0°C
Correct answer is option 'B'. Can you explain this answer?
a)
below 4°C
b)
at 4°C
c)
above 4°C
d)
at 0°C
| | Focus Academy answered |
Water has a special property of maximum density at 4°C. At this temperature, water occupies least volume and becomes heaviest. This helps aquatic life survive in cold regions.
Fishes are able to live even if lake’s upper layer becomes ice- a)density of water is less
- b)density of ice is more
- c)density of water of lake is more
- d)All of the above
Correct answer is option 'C'. Can you explain this answer?
a)
density of water is less
b)
density of ice is more
c)
density of water of lake is more
d)
All of the above
| | Focus Academy answered |
Water is densest at 4°C and stays at the bottom of lakes. Ice floats on the top layer and forms an insulating cover. This allows aquatic life to survive in the lower liquid water.
Characteristic of pure water is- a)presence of harmful microorganisms
- b)impure and odorous water
- c)presence of chemicals
- d)presence of oxygen in adequate amount
Correct answer is option 'D'. Can you explain this answer?
a)
presence of harmful microorganisms
b)
impure and odorous water
c)
presence of chemicals
d)
presence of oxygen in adequate amount
| | Prof. Sonal Sharma answered |
Pure water is clean, colourless and free from harmful impurities. It should contain adequate dissolved oxygen for supporting aquatic life. Hence, presence of oxygen in adequate amount is correct.
Drinkable water on Earth is- a)97.2%
- b)2.15%
- c)0.65%
- d)0.0%
Correct answer is option 'D'. Can you explain this answer?
a)
97.2%
b)
2.15%
c)
0.65%
d)
0.0%
| | Prof. Sonal Sharma answered |
Most of the Earth’s water is salty and not drinkable. Only a very small part of fresh water is available for human use. Hence, drinkable water is nearly 0.0% when compared to total water.
In summers, wet clothes dry very fastly due to- a)condensation
- b)evaporation
- c)Neither (A) nor (B)
- d)Both (A) and (B)
Correct answer is option 'B'. Can you explain this answer?
a)

b)
evaporation
c)
Neither (A) nor (B)
d)
Both (A) and (B)
| | Prof. Sonal Sharma answered |
Heat in summer increases the rate of evaporation. Water from wet clothes turns into vapour quickly and escapes into air. Therefore, clothes dry fast due to evaporation.

Heavy water is written as D₂O where D represents deuterium. It is different from normal water which is H₂O. Hence, D₂O is the correct formula of heavy water.
In hilly areas, water pipelines burst during winter because- a)water expands after freezing
- b)water squeezes after freezing
- c)pipelines squeeze at freezing
- d)None of the above
Correct answer is option 'A'. Can you explain this answer?
a)
water expands after freezing
b)
water squeezes after freezing
c)
pipelines squeeze at freezing

When water freezes, it expands in volume. This expansion puts pressure on pipelines and may cause them to burst. Hence, the reason is expansion of water after freezing.
Water in earthen pot remains cool due to- a)condensation
- b)evaporation
- c)sedimentation
- d)sublimation
Correct answer is option 'B'. Can you explain this answer?
a)
condensation
b)
evaporation
c)
sedimentation
d)
sublimation
| | Aspire Academy answered |
Earthen pots have tiny pores through which water slowly seeps out. This water evaporates from the surface and takes heat from the pot. Therefore, water remains cool due to evaporation.
Main cause of water level depletion is- a)urbanisation
