Application: Laboratory or teaching |
Experimental method
First, ignite the candle, put on the air duct, and place the candle in the middle of the bottom of the air duct to observe the rotation of the upper blade, and extinguish the candle blade to stop rotating. The experiment shows that the hot air is generated after the candle is ignited, and the convection of the hot air and the external cold air forms a wind in the air duct, which proves that the wind is formed in this way.
Precautions
1. Continuous combustion should not exceed 1 minute, so as not to affect the deformation of the duct.
2. If the blade is difficult to turn, use your hand to gently move the blade.
3. The air duct is made of transparent plastic to avoid contact with chemical liquid of methyl propylene.
