Melting of Wax Is a Physical Change but Burning of Wax Is a Chemical Change

Melting of Wax Is a Physical Change but Burning of Wax Is a Chemical Change. Explain?

Wax melting is a physical transformation. When wax is melted, it transforms from a solid to a liquid condition. It’s a reversible reaction that produces no new chemicals.

The wax reacts with the oxygen in the air once more, forming carbon dioxide, heat, and light. As a result, both shifts are accompanied by the candle’s burning.

As a consequence, candle burning is both a physical and a chemical transformation.

• The substance involved in a physical change is structurally identical before and after the change. Texture, shape, temperature, and a change in the state of matter are examples of physical changes. A change in a substance’s texture corresponds to a change in its feel. When you run your finger across a block of wood, it may seem rough, but scraping the wood with sandpaper smooths the surface so it no longer feels rough. The wood did not transform to become a new material during the sanding process; just the texture of the surface changed.
• When the chemical makeup of a substance changes, it necessitates the breaking and formation of chemical bonds during a chemical reaction. As a result, atoms in substances are rearranged to generate chemical reaction products, which are brand new molecules that are difficult to return to their original condition.
