Most chemical changes happen between molecules, so they are unseen.
Physical changes occur more often on Earth compared to chemical changes. Physical changes involve alterations in the state or appearance of matter without changing its chemical composition. Examples include changes in shape, size, or state of matter (solid, liquid, gas). Chemical changes involve the formation of new substances with different chemical properties.
No, changes in state of matter (such as melting, freezing, boiling) are physical changes, not chemical changes. Chemical changes involve the formation of new substances with different chemical properties.
Physical changes are changes that affect the form of a chemical substance, such as changes in state or shape, without changing its chemical composition. Chemical changes, on the other hand, result in the formation of new substances with different chemical properties. Physical changes are usually reversible, while chemical changes are often irreversible.
physical or chemical changes
some chemical changes can be reversed but they are hard to reverse usually
Physical change, if it changes in a way to be seen, or chemical change, which if the change can not be seen
chemical .
Not all chemical changes are accompanied by a visible physical change. Most chemical changes however will be accompanied by a physical change.
Heat usually accelerates any chemical changes
A temperature change can be seen both in physical and chemical changes.
Physical processes is changes that can be seen from the eye. These changes affecting the form of a chemical substance but does not change its chemical composition.

Sensors of varying nature can measure the physical and chemical changes in the Environment. At present, there are no instruments that can measure both physical and chemical factors.
The most important changes are of chemical nature; water evaporation is a physical process.
I am also researching on this. Cant seem to find answers anywhere. I am also researching on this. Cant seem to find answers anywhere. There is the formation of a precipitate seen when baking a cake or making eggs. A color change indicative of chemical changes can be seen in the browing of meat or potatoes. Hope this helps.

There are no physical changes. there are only chemical changes.
