  • B. The melting of candle wax
  • C. The decomposition of food
  • D. The rotting of leaves
  • E. The lightening of a match stick
  • F. None of the above

Chemistry

ANSWER: The melting of candle wax

The melting of candle wax is a physical change and not a chemical change.

In a chemical change, a new substance is formed and whatever substance is formed can't be reversed to what formed it.

When candle melts, the composition of substances in the melted candle is still the same as that of original candle. The only difference is that it changed its state from solid to liquid. If left to cool for some time, the liquid candle wax will change its state back to solid. For this reason, both the solid candle and the melted candle wax will have the same composition and chemical formula.

A similar process happens when water is put in a freezer. The liquid water only changes its physical state to solid water (ice) but its composition and chemical formula remains the same (H2O).

Note: The melting of candle is a physical change while the burning of candle is a chemical change.
