all physical changes can be identified at the macroscopic level. true or false

The physical changes are reversible in most cases and these changes are not the chemical changes which means that it is only the change in its state not in their nature. Just take the example of water, on cooling it becomes solid and change in color can be seen which is white in solid form and colorless in liquid form. This is also reversible and is a physical change. This means that physical changes can be identified at macroscopic level. Hence the answer is true.

It is TRUE that all physical changes can be identified at the macroscopic level.

WHAT IS A PHYSICAL CHANGE:

A physical change is a change that does not affect the chemical composition of the substances involved.

Physical changes do not form new substances and are often easily reversed. Physical change include change of states or morphological changes in form of substances.

Since physical changes do not involve any chemical reaction, they can be easily observed with the naked eyes i.e. macroscopically.

Therefore, It is TRUE that all physical changes can be identified at the macroscopic level
