Air is composed of several gases, including oxygen, and fire needs oxygen to burn. You can demonstrate this by lighting a small candle and then placing a drinking glass over it; the candle will burn up the oxygen trapped in the glass, and then the flame will go out, since fresh oxygen from outside the glass is unable to replace it. But as the candle burns up the oxygen, it produces carbon dioxide and water vapor, because the candle is made up of paraffin, a hydrocarbon (C25H52). The formula for this reaction is: 2 (C25H52) + 38(O2) = 25(CO2) + 26(H2O) You know that the drinking glass is cold, from room temperature, but
