Answer 2

Answer:

The correct answer to this question is BOTH B AND C

Explanation:

Given - A physical change

To Find - Write which of the following represents a physical change.

BOTH B AND C represent a physical change.

A physical change, which is often reversible in nature, is one in which a substance experiences a change in its physical characteristics, such as form, size, color, condition, or appearance.

The chemical makeup is not altered throughout these physical changes, and no new material is created.

An example of a chemical change is the burning of paper and wood.

Because in this case, while heating paper or wood, ash is produced that differs chemically from the original materials.

The process is also irreversible since we cannot make paper from ash again.

Therefore, burning wood and paper results in a chemical change.
