Question

Assertion :The burning of a candle is both a physical and a chemical change. Reason: Burning of candle melts the wax and hence physical state of wax has changed from solid to liquid. Again the wax combines with the atmosphere oxygen and changes to carbon dioxide, heat and light.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion

• D. Both Assertion and Reason are incorrect

Answer 1

Answer: (A)

Burning of the candle is both physical and chemical change. Burning of the candle melts the wax and hence physical state of wax has changed from solid to liquid.

Again the wax combines with the atmospheric oxygen and changes to carbon dioxide, heat and light.

Thus both the changes are accompanied by the burning of the candle.
