Question

Once, Paheli visited a tailor shop and brought home some cuttings of fabric to study their
properties. She took two pieces and found that one of the pieces were shrinking when it was
burnt with a candle. However the other did not shrink on burning. Can you help her to find
out which of the two was a cotton fabric and which a silk fabric?

Answer 1

Answer:

The silk has a protein present in it. So the silk fabric had shrunk and the cotton fabric did not.
