It is a chemical change. The reaction is combustion
its a chemical change because smoke and ash the new materials are formed
It is a chemical change as butane undergoes combustion to produce water amd carbon dioxide.
Yes, butane burning is a chemical change. The molecule of butane is converted to CO2 and H2O when combusted in oxygen.

Chemical.
A physical change
Physical change of the paint, not the door.
the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.
A physical change is reversible, a chemical change is not.
Physical... chemically, it's still the same substance,
lighting is a chemical change
its an chemical change because roasting over a campfire the meat will be roasted so its chemical
Lighting a match is a chemical change.
It is a chemical change.
Mainly chemical (oxidation).
The chemical changes are in the campfire- the wood combines with oxygen from the air, releases heat and carbon dioxide. The water does not have a chemical change, but does have a physical change- it changes from a liquid (water) to a gas (steam).
This is a little tricky. Striking a match is a physical act, but it does induce chemical changes. It depends on exactly what you mean by "lighting", ultimately. The end result is definitely a chemical change.
Light is a form of energy, not a change. Light can be produced by both chemical changes (such as fire), and physical changes (such as very high velocity impacts).
lighting a match from a matchbox is a chemical change.
There is a few signs of a chemical change that you see in a campfire. You can tell by the color, temperature and burning.
yes lighting a match is a chemical change
Examples of chemical changes: * Burning of paper * Rusting of iron Examples of physical reactions: * Melting of ice * Melting of wax
