1.  When  sulphur burns it first turns into blood red liquid form and then into a gas emitting a blue flame. It is best visible in dark. The gas formed is Sulphur dioxide. SO2 has a peculiar suffocating odor.  If all the air is consumed in burning and no fresh air goes in to the tube, burning will stop. Otherwise, all sulphur will burn.
