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.
Physical changes involve changes in appearance, state, or form of matter without changing its chemical composition. Signs of physical changes include changes in size, shape, color, or state (solid, liquid, gas). Chemical changes involve the formation of new substances with different properties. Signs of chemical changes include temperature change, gas production, formation of a precipitate, or color change.
Origami is a physical change because it involves the folding and manipulation of paper without altering its chemical composition.
A physical change that does not produce a new substance is called a reversible change. This means the change can be undone by reversing the process, such as melting or freezing.
It's a physical change why are some people f$#@%ing stupid and saying a chemical change??

Withdrawal,Addiction, and Tolerance.
what is the answer
A physical change to a substance is a change in its state. This means that the substance goes from a solid to a liquid or gas, or vice versa.
change in the form -in general can be indicated for the physical form. The substance may dissolve or its stage may change. If the change is physical, it should be reversable.
solid,liquid,or gas
hydrogen and oxygen gas are given off

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. A burning candle is a chemical change, both can occur at the same time.
