Slow bubbles

Exhibition Name: Slow Bubbles Example Introduction: Inflate the container bottom with an inflation device. The audience can see that during the rising process of bubbles, as the pressure gradually decreases, their volume gradually increases, thus allowing the audience to understand Boyle's law, which states that under constant temperature and other conditions, the pressure and volume of a gas are inversely proportional. Parameters: Size: 2 × 0.5 × 2M Function: The inflation device inflates the bottom of the container. The audience can see that during the rising process of bubbles, as the pressure gradually decreases, their volume gradually increases, thus allowing the audience to understand Boyle's law, which states that under constant temperature and other conditions, the pressure and volume of a gas are inversely proportional. Technical parameters: 1. Transparent acrylic round tube: φ 400 * 10mm. 2. Liquid inside the tube: silicone oil, water. 3. Height of the pump handle: 700mm. 4. Leakage protection: DZ47LE-32/C10, national 3C certification. 5. Transformer: AC24V 30W. 6. LED light: AC24W 18W IP68. Operation method: Use the pump to continuously inflate and observe the rising bubbles in the glass column; Observe the volume change of bubbles during their ascent.
