a physical change can be reversed a chemical one can't
A chemical change is when a new substance, with new and different properties, is produced. The identity of the original substance is changed. In contrast, a physical change is when one or more of a substance's physical properties have simply been altered; no new substance is produced.

Is a change that produces a new element a physical change?

No, it is a chemical change. ---------------------------------- Yes, it is a physical change because this change not involve a chemical reaction but a nuclear reaction followed by a change in the number of protons and neutrons.


How are physical and chemical changes different in two ways?

a physical change can be reversed but a chemical changes is not. you can all tell the different from a physical and chemical change by seeing if the color or if the substances is still in it normal element and it a chemical change if it has been change to a new substances like a burn paper change to Ashes. It is all most a physical change but it can not be reversed back.


How is a physical change different than a chemical 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


When rust forms on a car is that a physical change?

The formation of rust on a car is a chemical change, not a physical change. It occurs when the metal reacts with oxygen and moisture in the air to form iron oxide. This process alters the chemical composition of the metal, making it different from its original state.


When gold changes from a solid to a liquid is that a physical or chemical change?

The change from a solid to a liquid is a physical change, as the substance's chemical composition remains the same. Physical changes affect the state or form of matter without altering its chemical composition.

When do the physical and chemical properties change?

Physical and chemical properties change as the result of a chemical change, which produces new products with different physical and chemical properties than the reactants.


When substances are formed that are different from the starting substances has physical change occurred?

No, a physical change refers to a change in the form or appearance of a substance without any change in its chemical composition. If new substances are formed with different chemical properties, then a chemical change has occurred, not a physical change.
