Which is the only common metal that is liquid at room temperature?
Mercury
When a fire is caused by an electric short circuit, why must you not throw water?
If you throw water on a fire caused due to short circuit, you may be electrocuted because water is a good conductor of electricity.
Why do we see lightning much before we hear thunder?This is because light travels much faster than sound. Light travels @ 2.99 x 108 mt / sec (2,99,000 km/sec) whereas sound travels @ 333 mt/sec.
Which planet is the closest to the Sun?
Mercury
Which is the hottest planet?
Venus
How much time does the earth take to complete a revolution around the sun?
365 % days.
Why are whales hunted?
For the blubber or the oil in them.
Where do platypuses live?
In burrows near water.
How many days does the moon take to go round the earth?
27 1/3 days.
Among the insects that are extant, (that are living still), which is the most ancient?
Cockroach.
What is meant by fulcrum?
Fulcrum is the point about which a bar or lever will rotate, when a force is applied at any distance from that point or axis.
What kind of leaves do silkworms thrive on?
Mulberry leaves.
Why is it dangerous to look at die sun during an eclipse?
During solar eclipse, the ultraviolet rays are in such high proportion in sunrays, that they can cause irrepairable damage to the eye.

What is cholesterol?
Cholesterol is a fat found in the human body and the body of other large animals. In its pure form it looks like white sugar. It is made up of tiny crystals, which can be seen under a microscope. It is said that too much cholesterol in the blood is responsible for the hardening of arteries and for various other heart ailments.
How did the watch get its name?
From the fact that you have to watch it to know the time.
What is vulcanisation of rubber?
The process of hardening rubber by adding sulphur and heating the mixture is vulcanisation. Vulcanisation was discovered by Charles Goodyear. Raw rubber is sticky. It hardens when the temperature is low and softens when it is high. Charles Goodyear discovered that by combining raw rubber with sulphur and by heating it, the rubber becomes stronger and elastic and also resistant to solvents. Today almost all rubber, whether natural or synthetic is vulcanized.
When faced with danger what does a Pangolin do?
It rolls into a ball.
