I have this same worksheet that has the following questions that I have to answer: Iron rusts. Sodium hydroxide dissolves in water. A safety match ignites and burns. A cube of ice melts to form a puddle of water. Icicles form at the edge of a rof. Water is heated and changed into steam. Milk goes sour. A chocolate bar melts in the sun. Acid on limestone produces carbon dioxide gas. Vinegar and baking soda react. A tea kettle beings to whistle. Wood and leaves rot to form humus. So, I believe that a safety match igniting and burning is a chemical change. I have many Wiki results from that, and some put physical change. I don't think it's a physical change because the fire is on the match, and once it blows out, it creates that black substace which ISN'T fire. It creates a new substance that wasn't there before. Basically, the red part of the match and the fire created that new substance. I hope this helped! Sorry if this is wrong info. *-*
Burning anything is a chemical change. When something burns, the molecules of the substance are combined with oxygen, breaking the bonds in the molecule and forming new ones.

chemical change since if you are burning wood it would turn into ash which has a different chemical composition than wood. You can undo a physical change but you cannot do the same to a chemical change.
It is a chemical change because the wood and oxygen are changed into new substances, carbon dioxide and water.

Examples of chemical changes: * Burning of paper * Rusting of iron Examples of physical reactions: * Melting of ice * Melting of wax
Chemical, because it changes into another substance after burning.

A match burning is a chemical change. Salt dissolving in water is a physical change.
it is a chemical change.... so i would assume it is a chemical matter. it is a chemical change because of phosphrosus on the end of the match changes in to co2

Lighting A Match
Water evaporating is only a physical, not a chemical change because the water can be brought back easily to its original state where as burning a match is a chemical change.
Lighting A Match
Mainly chemical (oxidation).
