Intermolecular forces

Simulate intermolecular forces by pulling the disc out of the water to understand how intermolecular forces are generated. The exhibits consist of metal plates, circular sinks, pulleys, ropes, spring force gauges, etc. The exhibit the process of pulling a disc out of water through experiential settings, allowing visitors to experience the intermolecular forces between water molecules, which are the result of electrostatic interactions. Target audience: Adolescents aged 6-15 years old. Interactive display device operation instructions (audience experience) 1 visitors slowly pulls the rope, observes the reading of the spring force gauge, and feels the difference in the amount of force applied at different time periods; 2. Read the text and understand how intermolecular forces are generated. A description of the intrinsic connections between storylines and exhibits, as well as the fundamental knowledge of chemistry and the intermolecular forces.

Interaction type: Interactive installation. The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

Intermolecular forces, also known as van der Waals forces, are the result of electrostatic interactions and exist between neutral molecules or atoms. The intermolecular forces change with the distance between molecules. When a molecule moves away from its equilibrium position at a certain speed, it undergoes a deceleration motion, converting kinetic energy into molecular potential energy. Reference materials.
