Answer 1

Answer:

Answer 2

Irreversible changes:

Changes that cannot be reversed, that is, we cannot get back the original substance by changing the conditions that brought about the change, are known as irreversible changes.

Non biodegradable waste:

Waste that cannot be decomposed or degraded by microbes, are known as non biodegradable waste.

Land fill:

A landfill site, also known as a tip, dump, rubbish dump, garbage dump, or dumping ground, is a site for the disposal of waste materials. Landfill is the oldest and most common form of waste disposal, although the systematic burial of the waste with daily, intermediate and final covers only began in the 1940s.

Evaporation:

The process by which a liquid gets converted into its vapour state under its boiling point is known as evaporation.
