A PHYSICAL CHANGE MEANS CHANGE IN EXTERNAL APPEARANCE .
A CHEMICAL CHANGE MEANS THE CHANGE IN THE PARTICLES BY WHICH IT IS MADE up OF.
Physical Changes are d changes which are reversible .In this change we can get the products back. eg-Mixing of water and salt ,we can get salt back .
Chemical changes are d changes which are irreversible . In this change we cannot get the products back . eg- Burning of candle , we cannot get the matchstick back after burning .
Chemical Change: A chemical change is a reaction that transforms (changes) a substance into a new substance or substances with different properties.
Physical Change: No new substances are made. It is fairly easy to reverse this kind of change. An example would be dissolving salt in water. The change can be reversed simply by evaporating the water.
A phsical change is when something changes from a solid to liquid, liquid to ect. ect. The substance is still the same.
A chemical change is when the structure of the atoms in something change eg a metal forming a metal oxide or cooking an egg.
Physical changes do not change the makeup nor the properties of a substance, Cut a large piece of paper, and it is still paper.
Chemical changes like burning paper --- you can't write on it anymore. Properties have changed because the makeup has changed.
physical: what changes on the outside
chemical:what changes on the outside
a physical change is reversible but a chemical change is not ora physical change is a change in which no new substance is formed; a chemical change is were one or more substances are formed

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.
Is burning a fire a physical or chemical change?
Burning is a chemical change.
Is cutting a paper physical or chemical change?
It is a physical change because it is still a sheet of paper.
How do you illustrate chemical change versus physical change in a venn diagram?
by drawing 2 circles and compare and contrast chemical and physical change
How do you know if a chemical change has occurred versus a physical one?
A chemical change results in the formation of new substances with different chemical properties, such as changes in color, odor, or the formation of gas or precipitate. A physical change, on the other hand, only affects the physical state of a substance, without changing its chemical composition.
Is stapling an envelope a physical change or chemical?

Are tarnishing and rusting physical or chemical changes?
Tarnishing is a chemical change as it involves a reaction with the metal's surface, often due to exposure to air or moisture. Rusting is also a chemical change, specifically the oxidation of iron in the presence of oxygen and water. Both processes result in the formation of new compounds on the surface of the material.
Is pounded metal a physical or chemical change?
Physical change
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.
