Neither. You are neither creating a new substance nro are you changing the state of another. You are halitng a chemical change.

It's not really either. There are no chemical changes involved in blowing it out. The chemicals and elements remain as they are. But there isn't really a physical change either. Like the first guy said, you are just stopping a chemical change.

A burning match represents an ongoing chemical change. The sulfur, phosphorous, and whatever else is in a match is reacting with oxygen from the air to produce heat, light, carbon dioxide, and oxides of phosphorous, sulfur and the rest of the match components.
When you blow the match out, you've stopped the reaction, so while it wouldn't strictly fall under the title of a chemical change, that's what it's closest to.

It's a chemical change

i dunno much about science but the way i look at it is ..... u have the sulpher and other compounds that are stable untill u add a heat source which ignites it. when u blow it out u are adding carbon dioxide to the mixture. the lack of oxygen dur to the high carbon dioxide puts it out.
then again windy day will blow out the match and that is high oxygen
dunno if any of that helped or makes it worse
