why?

It cools towards room temperature so it does not freeze

## Ans 7:

Class : Class 8
at 4 degree celsius water starts expanding and 'x' shows the same the room temperature might have been near or equal to the freezing point of water(eg room temperature of regions like arctic and antarctic)

Class : Class 6

## Ans 9:

Class : Class 7
I think B is the correct answer because there is no solidification taking place or else the water would have turned into ice. plus no solidification can take place when water is at room temperature.

## Ans 10:

Class : Class 8
Also freezing and melting point of water is 0 degrees celsius

## Ans 11:

Class : Class 8
It is cooling towards room temperature so it does not solidify since the freezing point is below room temperature.

I think b is correct because there is no solidification

## Ans 16:

Class : Class 7
B should be the correct answer I think

## Ans 17:

Three states - gas , liquid & solid When hot water temp is going down it will be ultimate become solid ie ice But before becoming ice temp will stagnant for some time where in both states liquid & solid co-exist==> some part of liquid is in ice form. X is the same state where in solid and liquid will co-exist. Hence option 4 is correct(solidification& evaporation) Note: Could not attach gif .It would have made it more clear.

Both plants ‘c’ and ‘d’ bear fruits. This means they are flowering plants as only flowers change into fruits. Plant ‘c’ grows in water i.e., it is an aquatic plant but plant ‘d’ does not grow in water thus, it is a nonaquatic plant. Hence 'W' and 'X' represent plant ‘c’ and ‘d’ respectively.

How can a liquid be equal to a battery and another liquid be equal to *its* cell?

Class : Class 8
How can a liquid be equal to a battery and another liquid be equal to *its* cell?

In given figures, both the circuits are tightly connected and both the liquids conduct electricity because both the bulbs are glowing. The bulb in the set up P glows more brightly as compared to that of the set up Q might be because of any of the two possibilities:

1. The liquid in Q may have small conductivity.

2.  Liquid in P is equivalent to a battery while liquid in Q is equivalent to a cell of the battery of liquid P

Ans.- (A) The buggy pulls the horse as backward just as hard the horse pulls the buggy forward. According to the IIIrd law of NLM( Newton's Laws of Motion), the action and reaction force takes place in two different bodies, in different direction , but of the same magnitude.

Class : Class 8

## Ans 5:

Class : Class 8
Answer A will be correct if you take newtons third law of motion into consideration

Class : Class 1

The buggy pulls the horse backward just as hard as the horse pulls the buggy forward. Both of them would not move forward if surface is frictionless.

In the given Venn diagram X, Y and Z represent vitamin D, vitamin E and vitamin K, respectively. Deficiency of vitamin A causes night blindness and deficiency of vitamin C causes scurvy. Pellagra is caused by deficiency of vitamin B3. Vitamin B is a group of several vitamins like B1, B2, B3, B6, B12 and folic acid and is known as vitamin B complex.
