Question

A change in which the form of matter is altered but one substance is not transformed into another is called:

• A. Physical change
• B. Chemical change
• C. Biochemical change
• D. Photochemical change

Answer 1

The correct option is A Physical change

A physical change is a change of the physical state. They are usually reversible. The physical properties of a substance include such characteristics as shape (volume and size), color, texture, flexibility, density, and mass.

Hence, we can say a change in which the form of matter is altered but one substance is not transformed into another is called a physical change.

Therefore, option A is correct.
