Why is burning carbon not a chemical change?
But it IS a chemical change. When carbon burns in oxygen it forms carbon dioxide with the release of energy and the formation of a new substance. This is a chemical change and can be represented by the equation: C (s)+ O2(g) = CO2(g)

it happens when •A physical change is reversible, a chemical change is not.•the freezing of water would be a physical change because it can be reversed, whereas the burning of wood is a chemical change - you can't.
Is freezing carbon dioxide a chemical change or physical change?
Frozen carbon dioxide is still carbon dioxide, so it is a physical change.
