BulletPoint1 : *When the gas is compressed, the outside world does work on the gas, the internal energy of the gas increases, and the temperature rises. The air compression ignition device demonstrates the above phenomenon.
BulletPoint2 : *But the compressed gas, when it expands to do external work, its internal energy decreases and its temperature decreases. This demonstrator demonstrates the latter phenomenon.
BulletPoint3 : *The air in the cylinder is compressed, the temperature is increased, and the heat is gradually transferred to the outside.
BulletPoint4 : *As you continue to pump Yuanjian, the compressed air inside suddenly squeezes out the rubber plug, and suddenly produces a "pop" sound, the compressed air suddenly expands, and the temperature suddenly drops.
BulletPoint5 : *If you drop a few drops of alcohol in the cylinder in advance, the alcohol vapor will be condensed into a mist when suddenly cooled, which proves that the internal energy of the gas is reduced.

ProductDescription : Instructions:
1. Remove the rubber stopper, drop a few drops of alcohol, and then plug the rubber stopper tightly.
2. Use the pumping Jane to inflate the round Jane, to a certain extent, the rubber stopper is suddenly ejected by the compressed air in the cylinder, and at the same time it makes a popping sound.
3. Carefully observe the cylinder and find that "white fog" is produced in the Jane. This is where the sudden cooling of the air in Jane causes the alcohol vapor to condense into a mist.

Precautions:
1. During the demonstration, the rubber stopper should be facing upwards to prevent the rubber stopper from flying out and breaking the protective rope.
people.
2. The tightness of the rubber stopper is best practiced in advance. If it is too loose, the demonstration effect will not be achieved. If the sound is too loud when the stopper is too tight, it may affect the order of the class.
3. Before the demonstration, it is best to check whether the circle is cracked to ensure the safety of the experiment.
