Physical Change: A change in which the atoms or molecules in a substance stay the same.
Example: Ripping a piece of paper in half
Chemical Change: A change that affects the type of molecules or atoms in a substance.
Example: Burning wood
The primary difference is that in a physical change, the composition of the substance remains the same, but in a chemical change, the composition of the substance changes.

What are the signs of physical change from a chemical change?
Signs of a chemical change include the formation of a new substance, a change in color, production of gas or bubbles, release of heat or light, and a change in odor. These changes are not easily reversible and often involve the rearrangement of atoms.

Is melting wax a physical chemical or nuclear change?
This is a physical change, not a chemical change! It is because all the wax is still all there as for if it was a chemical change it would be all gone!Physical. Its physical state changed from solid to liquid. It's chemical make up remains the same.Melting wax is a chemical change because a new substance is forming. Trust me im intelligent and we just learned this in science.physical change :)It is a chemical change because it gives off heat even when it is burning. heat is one of the signs that tell whether it is physical or chemical change. The signs are heat , light's ,gas,discolor.Melting was would be a physical change-- no chemical reaction occurs when something melts or boils.
