Answer 1

Chemists study physical and chemical changes. Physical changes do not alter the identity of a substance, while chemical changes occur when one substance is turned into another substance. Observations that indicate a chemical change include color change, temperature change, light given off, formation of bubbles, and formation of a precipitate.

Step-by-step explanation:

Chemists make a distinction between two different types of changes that they study-physical changes and chemical changes. Physical changes are changes that do not alter the identity of a substance. Chemical changes are changes that occur when one substance is turned into another substance. Observations that indicate a chemical change has occurred include color change, temperature change, light given off, formation of bubbles, formation of a precipitate, etc.
