a chemical change
The mass of a substance does not change when the amount of the substance changes. The temperature of a substance does not change when the amount of the substance changes. However, the volume of a substance may change when the amount of the substance changes, depending on the conditions.
A change that alters the form of a substance without changing it into another substance is called a physical change. This type of change does not involve a change in the chemical composition of the substance, only its physical appearance. Examples include changes in state (solid to liquid) or changes in shape (cutting or crushing).
