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.

Ans 10:

Aditya Sai Vemparala from Amanora school, Pune

Also freezing and melting point of water is 0 degrees celsius

Ans 11:

SOUVAGYA SAHA from De Nobili School, DHANBAD

i think there is no option correct in this ques. no evaporation and boiling is taking place as it is cooling down towards the room temperature. also no condensation is taking place as in the ques it is written a HOT liquid is being transferred to a beaker. as well as solidification may also not take place because room temp is above 0 degree centigrate. SOF PLEASE SEE TO IT THAT THIS TYPE OF WRONGG QUESTIONS AND SOLUTIONS ARE NOT POSTED.

The correct answer is A.

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.

The correct answer is B

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.
