Advanced Air Pressure Micro Interpretation Demonstrator for Precision Analysis
1, Purpose:
Simulate the motion of gas molecules to explain the generation of gas pressure and microscopic phenomena such as gas laws.
2, Usage and principle:
1. Simulation of gas pressure
Connect the DC power supply DC10V (with two terminals marked in the diagram), turn on the power switch, adjust the variable resistor in the circuit to make the motor rotate at an appropriate speed. The plastic ball moves irregularly under the action of the vibrating plate, and the movement of the plastic ball impacts the movable disc, causing it to rise to a certain height. In this way, the total impulse of the ball on the disc per unit time simulates the pressure generated by gas.
2. Qualitative simulation of isothermal changes in gases:
When the motor speed is constant, it means that the temperature of the gas remains unchanged. When a heavy object (such as a gasket) is added to the guide rod, the volume of the gas decreases.
3. Qualitative simulation of isobaric changes in gases:
Keeping the counterweight added to the movable disk unchanged, increasing the motor speed simulates an increase in gas temperature. At this point, the movable disk can be seen rising to a higher height, indicating an increase in gas volume.
4. Qualitative simulation of isovolumetric changes in gases:
To increase the speed of the electric motor (simulate temperature rise) and maintain equal capacity, a counterweight (gasket) must be added to the movable disk guide rod to indicate that when the gas volume remains constant, the temperature rise leads to an increase in pressure.
