Ans 5:

nylon burns with a smell of plastic, not burning hair. WTF?

Ans 6:

Class : Class 8
Nylon does not have the smell of burning hair. So the answer should be d.

Ans 7:

Class : Class 10

Ans 8:

Class : Class 9
IT must be D! Nylon does not burn with the smell of burning hair as it is purely synthetic and has no relation to the protein based hair.

Ans 9:

Class : Class 8
IT SHOU BE D!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Ans 10:

Class : Class 8
Nylon should neither have a smell of burning hair nor the smell of burning paper. Nylon has a celery or plastic-like cell. Hence the correct answer is D. But on the other hand when acrylic burns, it shrinks and converts into black beads. On this contrast, the correct answer will be B with respect to acrylic and D with respect to Nylon. There is definitely an error in the options of the answers!

Ans 11:

Class : Class 8
Correct answer is A

Ans 12:

Class : Class 8
