Question

Smita wants to find new ways to recycle materials. Which field of study would be most useful to her?

Answer 1

Answer:

Option B

Explanation:

The chemical properties of a material play a very important role in recycling and reusing any thing.

For instance - if a plastic on melting transforms into a form which cannot be re-converted into its original form, then such plastics are not reusable materials

A recyclable material must be able to regain its original molecular structure and size though physical processes such as heating, melting, remolding etc.

hence, option B is correct  

Answer 2

Hello there!

The answer B.
It is not C. because that study has nothing to do with recycling. And it is not D either.

Hope this helps!
