Q 1) what r d 3 actions that bring about changes in matter? Elucidate it with an example

Answer 1

There are several actions that bring about changes in matter, in either it's shape, size, or state.

If you hit matter, it's shape and size can be altered. For example hit a can, or break a glass.

It's state can be changed by following six processes:

These phase transitions are as follows:
Melting: Solid to liquid
Freezing: Liquid to solid
Vaporizing: Liquid to gas
Condensing: Gas to liquid
Subliming: Solid to gas
Deposition: Gas to solid
