Specification
Brand : FYYKXWD
BulletPoint1 : Simulate the movement of gas molecules and explain gases
BulletPoint2 : Microscopic phenomena such as the generation of pressure and gas laws
BulletPoint3 : When the motor speed is constant, it means that the temperature of the gas does not change. When a weight is added to the guide rod (such as a gasket), the gas volume becomes smaller.
BulletPoint4 : To increase the speed of the motor (simulating an increase in temperature) and maintain the same volume, a counterweight (gasket) must be added to the movable disk guide rod. This simulates an increase in pressure when the volume of the gas remains unchanged, as the temperature increases.
BulletPoint5 : A rubber bottom plug is embedded on the base plate to make it easier to fix the thumbtacks. At the same time, the rubber strip is fixed with bolts, which is firm and easy to operate. The instrument has a simple and novel structure and is easy to operate.

ProductDescription : 1. Simulation of gas pressure
Connect the DC power supply DC14V (there are two terminals, marked in the picture), turn on the power switch, adjust the rheostat in the circuit to make the motor rotate at an appropriate speed, and the plastic ball will move irregularly under the action of the vibration plate. The movement of the ball impacts the movable disc and causes it to rise to a certain height, so that the total impulse of the ball against the disc per unit time simulates the pressure generated by the gas.
2. Qualitatively simulate the isothermal changes of gas:
When the motor speed is constant, it means that the temperature of the gas does not change. When a weight is added to the guide rod (such as a gasket), the gas volume becomes smaller.
3. Qualitatively simulate the isobaric changes of gas:
Keep the counterweight added to the movable disc unchanged, increase the motor speed, and increase the temperature of the simulated gas. At this time, you can see that the movable disc rises to a higher height, indicating that the volume of the gas becomes larger.
4. Qualitatively simulate the isovolumetric changes of gas:
To increase the speed of the motor (simulating an increase in temperature) and maintain the same volume, a counterweight (gasket) must be added to the movable disk guide rod. This simulates an increase in pressure when the volume of the gas remains unchanged, as the temperature increases.

Things to note:
1. The motor rotates at a high speed. Pay attention to the polarity of the motor power supply. Sometimes the positive and negative poles are reversed, which will cause the motor to get stuck and not rotate.
2. The motor current is relatively large during the experiment, and the power-on time should not be too long to avoid burning the motor.
