When a substance is cooled the molecules come closer. But there is no picture showing that the molecules are coming closer there is no correct answer. Also option B and C are the same. Can you please change it?

Ans 4:

The question , answer and the solution are all correct … Vrishank don't say that the SOF is mad ( I think you are mad ) you are a FOOL

Ans 21:

Class : Class 3
I agree with Harry , 1 B AND C ARE NOT THE SAME. 2 When liquid is cooled down it forms solid, SO THE ONLY ANSWER IS CCCC

Ans 22:

Class : Class 8
if an object is cooled down the molecule structure changes from loosely packed to tightly packed. therefore none of the options is correct

Ans 23:

Class : Class 6
All the options are totally wrong, please change them

Ans 34:

Class : Class 4
all are wrong

Ans 35:

Class : Class 5
I have by mistake typed it Co sorry it will be C. I have a solution we can report error.
