Explanation:

Physical change is an important concept in chemistry; it describes changes to things that don't result in brand-new substances. Physical change upholds the molecular structure of a substance. Water, for example, is composed of two hydrogen molecules and one oxygen molecule, no matter whether it's boiling or frozen.

While nuclear reactions also may produce new matter, nearly all the substances you encounter in daily life are the result of chemical changes. Chemical reactions help us understand the properties of matter. By studying the way a sample interacts with other matter, we can learn its chemical properties.
