Which of the following happens during a chemical change but does not happen during a physical change? (1 point) Atoms of one or more substances rearrange into a new substance. The appearance of a substance changes, but it is still the same substance The state of the substance changes The mass of the substance changes
Atoms of one or more substances rearrange into a new substance.
The correct answer is: Atoms of one or more substances rearrange into a new substance.
During a chemical change, the atoms of one or more substances rearrange to form a new substance. This means that option (1) occurs during a chemical change.
In a physical change, the appearance of a substance can change, but it remains the same substance. This means that option (2) can occur in both chemical and physical changes.
The state of a substance, such as changing from a solid to a liquid or a gas, can occur in both chemical and physical changes. This means that option (3) can also occur in both types of changes.
The mass of a substance, however, generally does not change during a physical change. In a chemical change, the mass of the substances involved may change due to the rearrangement of atoms and the formation of new substances. Therefore, the correct answer is option (4) - the mass of the substance changes, which happens during a chemical change but not during a physical change.
