The smoke from a match went in the chamber and traveled toward the heat source

(The candle).  The heat from the candle traveled through the air  and to the smoke. 

The smoke heated up, became less dense,  then rose to the top of the chamber. It

traveled across the top and as it traveled, it cooled down. When the smoke cooled,

it became more dense and sank to the bottom of the chamber.  The cycle continues

as the smoke travels towards the candle again.                                   Macey
