Question

Choose the correct option:
Statement I: The melting of wax is a physical change.
Statement II: The burning of wick for the production of heat and light is a chemical change.

• A. Both statements are true
• B. Both statements are false
• C. Only statement I is true
• D. Only statement II is true

Answer 1

The correct option is A Both statements are true

When we burn a candle, wax melts and hence the physical state of wax changes from solid to liquid. Thus, it is a physical change.
As the wick containing wax burns to produce flame, it combines with the atmospheric oxygen and changes to carbon dioxide, heat and light. Thus, it undergoes a chemical change. Hence, both the statements are correct.
