Answer:

False

Explanation:

It is not true that this is an example of a chemical reaction. This is a typical example of physical reaction.

Most physical changes are often phase changes.

  • A phase change is a change in the physical state of a body.
  • In this change, it is from solid to liquid.
  • Now new substances are formed.
  • When substances are changed from one form to another, it is a physical change.

In a chemical change, a new substance is formed at the end of the process.
