No, unless it reacted with a gas in the air around it. Melting is a physical change.

Is melting chocolate a chemical or physical reaction?
It is a physical state change from a solid to a liquid. It is not a chemical change, unless other ingredients are then added when melted - as usually happens when used in cooking, for instance.
Gun powder explodes is it a chemical or physical change?
Chemical, since it is no longer gun powder after the reaction, it is smoke.
A piece of solid gold that changes from a solid to a liquid is a physical or chemical change?
physical: it's a change of state, it does not change the chemical makeup: molecular, atomic
Is the formation of a solid a chemical change?
Yes, if it occurs as the result of a chemical reaction. For example, if two clear colorless solutions form a white precipitate (solid) when mixed, that would be an example of a chemical change. The formation of a solid from freezing is a physical change.
Is burned ethanol a physical or chemical change?
Burning anything (a liquid or a solid) is a chemical change and the reaction is known as a combustion reaction.
Does melted ice represent a chemical change?
no its a physical change because its changing from a solid to a liquid and its still water!
When you boil an egg does the water the egg or the pan undergo a chemical change?
Egg goes from liquid to solid. Water becomes steam, pan becomes hot. Cooking = chemical change.

Is a glass of juice frozen melted and refrozen a chemical or physical change?
physical :D I hope that helps
Why is a phase change like solid to liquid a physical change?
Melting, the phase change from a solid to a liquid, is considered a physical change rather than a chemical change because when the phase change takes place, the substance that was melted does not change its chemical composition, and the process could be reversed to get the original condition of the substance by freezing (liquid-solid).
Is melting butter a chemical change?
Partly physical, partly chemical. Melted butter has different chemical properties than solid butter. The melting process, as with chocolate, is not reversible. Proteins in the butter can become denatured, and isomerization of lipids to trans fats occurs. Phase change is a common example of physical change, but chemical change also occurs in this case.
What happened if overcook an egg?
Nothing much, it'll still be edible. The yolk will turn greenish though.
Gun powder explodes is it a chemical or physical change?
Chemical, since it is no longer gun powder after the reaction, it is smoke.
Is wax melting a physical or a chemical?
This is a physical change, not a chemical change! It is because all the wax is still all there as for if it was a chemical change it would be all gone!Physical. Its physical state changed from solid to liquid. It's chemical make up remains the same.Melting wax is a chemical change because a new substance is forming. Trust me im intelligent and we just learned this in science.physical change :)It is a chemical change because it gives off heat even when it is burning. heat is one of the signs that tell whether it is physical or chemical change. The signs are heat , light's ,gas,discolor.Melting was would be a physical change-- no chemical reaction occurs when something melts or boils. A burning candle is a chemical change, both can occur at the same time.
Is changing of a solid to liquid chemical or physical change?
No it is a chemical
A piece of solid gold that changes from a solid to a liquid is a physical or chemical change?
physical: it's a change of state, it does not change the chemical makeup: molecular, atomic
Is wax melting a chemical or physical or chemical property?
Physical change. The wax was solid and now it is a liquid. All phase changes are physical changes.
