Chemical Change: Fire

Ask a question What will happen when the fire from the match and the paper mix?

Construct a hypothesis( make a guess) My hypothesis is the the paper will burn after it is ignited with fire.

Conduct the experiment Paper and Fire

Record your observations and data colour change, The paper changed colour The heat/temperature of the paper The was a release of gas in the form of smoke It was irreversible A new substance was formed (Newspaper→Burned Paper)

Analyse information As all of these events have happened this is a chemical change.

Report results In conclusion, the paper and fire experiment is a chemical change. This is true because there was a change of colour as the paper turned from a white-grey to a dark black. There was also a severe change in heat/temperature. Not only that but there was also a large amount of gas released in the form of the smoke. It is also a chemical change because a new substance was formed in with the old substance being newspaper and the new substance was burnt paper this change is also irreversible.
