- Properties such as shape, size, color
and state of a substance are called its
physical properties. A change in which
a substance undergoes a change in its
physical properties is called a physical
change.
- when the new substance is formed then it is chemical change
- cutting of paper is physical change
- burning of paper is chemical change .note:when the is mansion in the reaction. it is chemical change
- Properties such as shape, size, colour

physical properties. A change in which
a substance undergoes a change in its
physical properties is called a physical
change. A physical change is generally
reversible. In such a change no new
substance is formed. - A change in which one or more
new substances are formed is called a
chemical change. A chemical change
is also called a chemical reaction.
- cutting of a paper is the physical change .
- burning of a paper is chemical change(when burning is mention in the given question it will become a chemical change)
- burning of a candle is both chemical change and physical change.

Is melting a change to metal physical changes?
melting is a physical change. freezing is also a physical change. the only thing that changed was the state of matter. a chemical change for example is buring, the substance changes to co2 and h2o.
What is a physical change of matter?
A physical change in matter occurs when the shape or form of matter changes, but there is no chemical reaction. If someone were to melt a sugar cube, that would be an example of a physical change.
What is example of Energy conservation?

Is boiling water an example of chemical change?
No, a chemical change is when a substance and forms one or more new substances, it changes its composition. examples: changes in color production of gas formation of precipitate Boiling water is an example of physical change, it can be any phase change.
When gold changes from a solid to a liquid is that a physical or chemical change?
It is a physical change (melting).
Is wood being carved an example of a chemical changes?

What are the chemical and physical changes of photosynthesis?
There are no physical changes. there are only chemical changes.
What is a non example of chemical changes?
non example of chemical change: one non example is ice. ice is NOT an example of chemical change.
Which is a example of a physical rather then a chemical change?
Freezing/melting or evaporation/condensation, are physical changes that don't affect the chemical nature of the substances.
Example of physical change and a chemical change?
when water changes to water vapour by heating is an example of physical change. when water is divided into oxygen and hydrogen by passing electricity is an example of chemical change.
Are state changes chemical or physical changes?
Physical Changes
Are all physical changes accompanied by chemical changes?
Not all chemical changes are accompanied by a visible physical change. Most chemical changes however will be accompanied by a physical change.
Differences between physical and chemical changes?
A physical change is a change that does not change the chemical makeup of the substance. This can be crushing, tearing, or a phase change for example. A chemical change changes the chemical makeup of the substance. Some examples of this are rusting, combustion, or digestion.
Chemical changes can be reserved by physical change?
No, chemical changes can only be reversed by chemical means, not by physical means.
What is an example of a physical change in baking?
both, because the ingredients are undergoing both physical and chemical changes such as: Butter melting= physical change Egg whites hardening= chemical change both, because the ingredients are undergoing both physical and chemical changes such as: Butter melting= physical change Egg whites hardening= chemical change
What is an emample of a chemical change?
The following are indicators of chemical changes: ... For example, changing the color of a metal does not change its physical properties.
Are phase changes physical or chemical in nature?
