What is changed when matter undergoes a physical change?
Answers
State of matter is changed which is often temporary.
PHYSICAL CHANGE
➡️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.
• Colour:- 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.
