Physical changes alter the form of a substance without changing its chemical composition, such as melting or dissolving. Chemical changes result in the formation of new substances with different chemical properties, such as burning or rusting. Testing for new substances formed or irreversible changes can help distinguish between the two types of changes.
you can tell if it is a chemical change when a brand new substance can be formed. The properties in a chemical change are flammibility or reactivity. A physical change no new substance is formed and is usually reversible but not in all cases.
Signs of a chemical change include: color change (two clear liquids producing a yellow liquid), phase change (two liquids producing a solid precipitate or a gas), temperature change (two liquids combining and cooling the solution down or heating it up).
physical is an original substance change by physical techiques. chemical is the same thing but chang by chemical techiques.
One way is perform a boiling point test or a melting point test.
you can tell the difference by a physical property is like an appearance and a chemical property is a change chemically like the density and if its soluble or not
A physical change does not change the chemical composition of the substance undergoing the change, however, a chemical change does cause a change in chemical composition.

What is the difference between a chemistry change and a physical change?
what is the difference between a physical change and a physical property
How does a chemical differ from a physical change?
A physical change is different than a chemical change, because in a physical change, the composition of the matter did not change. While in a chemical change, the composition of the matter did change.SO basically, the composition of the matter does not change is the difference between a physical change and a chemical change.yes

Alternate Wordings for 'What is chemical change and physical change and give its examples?
Explain the difference between chemical change and physical change, and provide examples of each. Define chemical change and physical change, and provide examples to illustrate. Differentiate between chemical change and physical change, and give examples to clarify the distinction.
What is the diffrenece between a physical change and a chemical change?
Physical change is a change in the structure. Chemical change is a change in the composition. Melting is a physical change. Complexing is a chemical change.
What is the difference between chemical change and physical change?
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 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 difference between physical changes and chemical change?
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 difference between a physical and chemical change?
A physical change is reversible, a chemical change is not.
What is the difference between chemical physical change?
a physical change is reversible but a chemical change is irreversible
What is the difference between a chemistry change and a physical change?
what is the difference between a physical change and a physical property
Difference between chemical and physical change?
A chemical change is when the chemical properties of a substance changes and a physical change is when the chemical properties stay the same but the physical properties (shape, temperature etc...)
What is the difference between a chemical and a physcial change?
chemical change is easily reversible whilst physical is not reversible
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 is one major difference in a physical change and a chemical change is?
One major difference between a physical change and a chemical change is in the composition of the substance. In a physical change, the substance retains its chemical composition and only its physical appearance is altered, while in a chemical change, new substances with different chemical compositions are formed.
What is the scientific difference between a physical change and a chemical change?
A physical change doesn't modify the chemical nature of the molecule.A chemical change transform the molecule A in another molecule B.
How does a chemical differ from a physical change?
