Answer 2

Answer:

1. (b) non-reversible /irreversible change.
2. (a) kilometre.
3. (c) both.
4. (c) both.

Explanation:

1. Non-reversible Change- water couldn't be attained back from the milk once mixed into it. Hence, it is an irreversible change.
2. Kilometre - the length of an object is measure in 'metres' and here, 'kilometres' shows the length of the material.
3. Both - material are classified on two basis - biotic(the living objects like human, plants, etc. ) and on abiotic (non-living objects like water, land, etc.)
4. Both- paper and vegetables easily break down to simpler forms and becomes humus and that is why, both of them are biodegradable substances.
