Answer 1

When a change in a physical property is observed, it could be caused by a change that is considered both physical and chemical. Chemists make a distinction between physical changes and chemical changes.

Step-by-step explanation:

When a change in a physical property is observed, it could be caused by a change that is considered both physical and chemical. Chemists make a distinction between physical changes and chemical changes. A physical change is a change in the form of matter that does not alter its identity. On the other hand, a chemical change occurs when one substance is turned into another substance, resulting in a change in the composition of matter.
