A piece of cobalt chloride is blue, but it is changed to light pink color when it’s moistened. A piece of aluminum foil won’t be burned when it is slipped over the wick of a burning candle. Investigation 1. Candles are usually made of paraffin, which is a mixture of hydrocarbons, substances that we find in petroleum. As the name implies, hydrocarbon molecules contain nothing but hydrogen atoms and carbon atoms. When they burn, they react with oxygen in the air. The carbon and the oxygen become carbon dioxide, while the hydrogen and oxygen become water. Both of these products are gases at the temperature of the flame, and they just go off into the air.

Capillary action is a physical effect caused by the interactions of a liquid with the walls of a thin tube. The capillary effect is a function of the ability of the liquid to wet a
