Answer 1

Physical change is a changes affecting the form of a chemical substance, but no its chemical composition. Physical changes are used to separate mixtures into their component compounds, but can not usually be used to separate compounds into chemical elements or simpler compounds......

Answer 2

➡️A physical change is a change to the physical—as opposed to chemical—properties of a substance. They are usually reversible.

➡️Physical changes are changes affecting the form of a chemical substance, but not its chemical composition.

➡️In a physical change appearance or form changes, but substance remains same.

➡️Common Physical Changes are:-

• Texture:-The texture of a substance can differ with a physical change.

• Color:- The changing of color of a substance is not necessarily an indicator of a chemical change.

• Temperature:- Although we cannot see temperature change, unless if a change of state is occurring, it is a physical change.

• Shape.

➡️Eg:- Ice on melting converts to water. Water on evaporation converts to water vapor. All the products formed are still forms of water. Hence, this is a physical change.
