Question

11 shemar and grace were investigating a place you could see both chemical and physical changes at the same time. they agreed that burning a candle was a good example. use their example of a burning candle, and explain where each type of change would be visible.

Explanation:

Physical change is when the form or state of matter changes without altering its chemical composition. In a burning candle, the melting of the solid wax into liquid wax is a physical change, visible near the base of the flame where the wax is heated. Chemical change occurs when a substance is transformed into a new substance with different chemical properties. The burning of the wax vapors in the flame is a chemical change, producing carbon - dioxide and water vapor, which is visible in the flame itself as the wax reacts with oxygen in the air.

Answer:

The physical change (melting of wax) is visible near the base of the flame where the solid wax turns into liquid. The chemical change (burning of wax vapors) is visible in the flame as the wax reacts with oxygen to produce new substances.
