Can wax change without changing state?

Can wax change without changing state?

In physical changes no new materials are formed and the particles do not change apart from gaining or losing energy. Melted wax solidifies when cooled but unless it is shaped or moulded it will not be the same shape as at the start.

Is melting wax reversible or irreversible?

melting of wax is a reversible change. Melting of was is reversible as it can be moulded in a candle. Burning of candle is an irreversible change but melting of wax is a reversible change as the wax can again be heated and shaped into desired shape..

What happens to the wax pieces?

When you light a candle, wax near the wick melts into a liquid. The heat of the flame vaporizes the wax molecules and they react with the oxygen in the air. As wax is consumed, capillary action draws more liquid wax along the wick. Both light and heat are radiated in all directions from a candle flame.

Is Melting of wax?

Melting of wax is temporary and wax can settle again on cooling and turns into a solid. Hence, the change is only physical and the state of matter changes.

Is melting wax chemical change?

The process of a solid becoming a liquid is called melting. Melting of wax, by itself, involves a change of state from solid to liquid. When the physical state of a substance changes, no new products are formed. Hence, melting of wax is physical change and the correct answer is option A.

What is the difference between melting of wax and burning of wax?

Melting of wax is physical change because only physical state is changing from solid to liquid but burning of wax is chemical change because in burning, wax reacts with oxygen present in surroundings and forms carbon di oxide and ash.

What kind of changes is melting of wax?

On heating, candle wax melts and form liquid wax. It is a physical change. Since it again turns into solid wax on cooling.

What is burning of wax?

Wax burning (Chinese: 煲蠟; Jyutping: bou1 laap6), also known as wax boiling, is the heating of candle wax to high temperatures in a container as a form of entertainment.
