A student observed liquid wax dripping down the side of a burning candle. After putting out the candle’s flame, the student left the room. Several hours later the student observed that there was no longer any liquid on the side of the candle. Which statement explains what most likely happened to the liquid wax?
F- The heat given off by the flame caused the candle wax to evaporate.
G The liquid wax changed back into a solid as it cooled.
H The liquid wax condensed and was absorbed by the candle.
J None of the above
G The liquid wax changed back into a solid as it cooled.
