Answer:
change in volume
Step-by-step explanation:
Chemical change is a type of change in which new substances are formed. There are various signs that indicate the occurence of a chemical change.
They include;
- Color change
- Formation of a precipitate
- Formation of a gas or bubbles
- Odor change
- Change in temperature
Therefore, in this case, change in volume is not an indicator that a chemical change has occurred.
