Why is a candle melting a chemical change?
Melting is accompanied by burning and thermal degradation - two chemical reactions.
Is burning a candle a chemical change or a physical change give reason?
It is both a physical and chemical change. The burning of the wick s chemical while the candle melting being physical.
Is welding pieces of metal is chemical change?
not it can always be changed back to its original shape. but if you burn metal which i dont consider doing it is a chemical change. like melting butter and burning butter. burning is chemical, melting can be cooled again into its original form.
What is an example of a physical change tarnishing rusting burning or melting?
Melting is an example of a physical change because it does not change the chemical composition of the substance undergoing the change. Tarnishing, rusting, and burning are examples of chemical change because they are caused by chemical reactions, which change the chemical composition of the substances undergoing the change.
Why is melting a physical property of the wax but flammability in a chemical property?
Melting doesn't change the composition of a compound (substance).Burning is a chemical reaction, an oxidation - new compounds are formed.
What are four examples of physical change?
Melting, Crushing, Mixing and Burning :)
Why is a candle melting a chemical change?

What is the chemical difference between melting and burning?
Melting is a change from a solid to a liquid. The molecules remain the same. Burning is a chemical reaction usually involving oxygen. It then changes into something else.
Explain why burning butter is a chemical change but melting is not?
Melting: change of phase, a physical phenomenon without change of the composition. Burning: a reaction of oxydation, a change of composition - a chemical change.
Is burning a diamond a physical change?
Burning is always a chemical change. Melting is a physical change.

What are the steps to prove that a burning of a candle is physical as well as a chemical change?
1. Melting of the candle is a physical change. 2. Burning and thermal decomposition are chemical changes.
What is an example of a physical change tarnishing rusting burning or melting?
Melting is an example of a physical change because it does not change the chemical composition of the substance undergoing the change. Tarnishing, rusting, and burning are examples of chemical change because they are caused by chemical reactions, which change the chemical composition of the substances undergoing the change.

What type of reaction occurs when a candle is burned?
There are 2; the melting of the candles wax is physical but the wick burning is chemical.
What part of a burning candle takes place and physical change?
The melting of the wax is a physical change. The burning the of wick is the chemical change
