Is A Candle Melting A Chemical Or Physical Change. Chemists make a distinction between two different types of changes that they study—physical changes and chemical changes. In a chemical reaction, there is a change in the composition of the substances in question; On heating, candle wax gets melted. The difference between a physical reaction and a chemical reaction is composition. Physical changes that involve a change of state are all reversible. In a physical change there is a. Since it again turns into solid wax on cooling. Melting of wax is a temporary and reversible change on cooling, wax solidifies, and no new product is formed while burning of a candle is a permanent. So, the melting of wax and. So, the difference between chemical and physical changes is that a chemical change alters the chemical composition of matter, while a physical change does not. When a candle burns, wax in the candle melts and is then vaporised as it is drawn up the wick. The melted ice cube may be refrozen, so melting is a reversible physical change. Melting and vaporisation are physical changes.
