Answer 1

A change in the phase of matter can be caused by a change in the amount of energy, such as heating or cooling the substance.

Step-by-step explanation:

A change in the phase of matter can be caused by a change in the amount of energy, such as heating or cooling the substance. For example, when a solid is heated, it can melt and change into a liquid. Similarly, when a liquid is heated, it can vaporize and change into a gas.
