Differences between physical changes and chemical changes?
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.
Changes in properties of matter are called?
physical or chemical changes
Is reacting a physical change or chemical change?
Reacting can involve both physical changes and chemical changes. Physical changes involve alterations in the physical state of a substance without changing its chemical composition, while chemical changes involve the formation of new substances with different chemical compositions.
Is physical and chemical changes a scientific method?
Chemical and physical changes are part of methods applied in science.
Write 3 differences between chemical and physical change?
Okay now here goes in a physical change no chemical reaction takes place. in chemical change chemical reactions take place. A physical change is reversible but a chemical change is not.In a physical change no new substance is formed(A+B=B) in a chemical change new substances are formed(A+B=C)
Similarities between physical and chemical changes?
well you know.......... why dont u tell me
What are two similarities between physical change and chemical changes?
They both are different kinds of air.
What are the similarities between oxidation and reduction?

what is the difference between chemical change and physical changes?
the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.

What is the differences between physical and chemical changes in relation to fire services?
Physical changes are melting and boiling in this case; fire is a combustion, a chemical change.
How can you tell the difference between physical and chemical properties?
You can tell the difference by knowing that a physical property changes shape and that a chemical property changes the substance.
What are some similarities and differences between physical and chemical weathering?
Similarities: Both processes result in the breakdown of rocks and minerals. Both can occur through natural processes like temperature changes, water, and biological activity. Differences: Physical weathering involves the physical breakdown of rocks into smaller pieces without changing their chemical composition, while chemical weathering alters the chemical composition of rocks through reactions with substances like water or acids. Physical weathering does not involve chemical reactions, while chemical weathering does.
What is the difference between a chemical change and physical change?
A physical change changes the physical properties of an element like color where chemical changes change the chemical properties of an element and usually can't be undone.
What are the chemical and physical changes of photosynthesis?
There are no physical changes. there are only chemical changes.
