Choose the statement that best explains the convection current in the chamber.

• Air above the candle flame gets heated.

• Warm air is less dense so it rises to the top of the chamber.

• As the warm air is cooled by the ice cubes, it becomes more dense and sinks to the bottom.

• As the air is heated again, the cycle continues.

• All of the above.
