The correct answer is A.

Sugar syrup is neutral and hence the colour of blue litmus and red litmus remains unchanged. Tamarind juice is acidic, so blue litmus turns red but red litmus does not change its colour. Lime water and soap solution are basic in nature which turn red litmus blue whereas blue litmus remains unchanged.

Ans 9:

Hritvi from Podar International School, Mumbai
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.

Hritvi from Podar International School, Mumbai
Class : Class 7
There is no proper solution for this question which will make it more confusing as everyone will have different opinions in this question.

Ans 11:

Sanidhya Kapoor from Shikshantar, Gurugram
Class : Class 8
It is cooling towards room temperature so it does not solidify since the freezing point is below room temperature.

Ans 12:

JANYA CHANGELA from UDGAM SCHOOL FOR CHILDREN , Ahmedabad
Class : Class 8
I THINK THAT B IS ONLY THE CORRECT ANSWER

Ans 13:

SOUVAGYA SAHA from De Nobili School, DHANBAD
Class : Class 10
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.

Ans 14:

kashvi from Amity, noida
Class : Class 7
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.

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.

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

Ans 4: (Master Answer)

Admin from revisewise, Noida
Class : Class 1

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.
