Answer 2

The disadvantages of Physical Changes are:-

• Physical Changes are the temporary changes that change the physical properties of the substance but the chemical composition remains the same.
• Physical changes are reversible changes without any chemical reaction taking place.
• For example, change in the state of the Matter of water, folding of paper, etc.
• During a physical change, the molecules rearrange their position rather than changing the composition of the substance.
• These physical changes do not cause pollution.

Disadvantages--

• Physical changes are not applicable if one needs to separate compounds from the constituent elements.
• For example, this process is not used to separate different components of salts.
• The most harmful effect of Physical change is that it causes Global Warming because it increases the amount of carbon dioxide and carbon monoxide.
