because they change the identity of the matter
it undergoes change, cause these changes may be temporary and easily reversible or may permanent and very difficult to reverse.
No, chemical changes are typically more difficult to reverse than physical changes. Chemical reactions involve the creation of new substances with different chemical properties, making it challenging to reverse the reaction and return to the original substances. Physical changes, such as changes in state or shape, usually involve rearranging the same particles and are more easily reversible.
The direction changes to the reverse
Irreversible changes.
"The problems you caused are irreversible; they can never be remedied."
Yes, it is difficult to make significant changes.
Evaporation is the reverse of condensation. Evaporation occurs when a liquid changes to a gas.
in most there is a small lever on the head. This changes the twist .
No, physical
Chemical changes are hard to reverse because they involve the formation of new substances with different chemical properties than the original substances. This typically requires energy input or a specific reaction pathway to revert back to the original substances, making the process difficult to reverse.
The chemical change produces one or more new substances, the physical change does not. Many people will tell you that the difference is that chemical changes can't be reversed, but this is an oversimplification used to help students when they are first learning about the types of change. In fact it's possible to reverse chemical changes, though it's sometimes quite difficult. Then again, some physical changes are hard to reverse too.
some people find it is difficult to make changes in one's life because they face a lot difficult decision everyday in life
