States of Matter - Atomic Bonding | Interaction Potential | Dipole - PhET Interactive Simulations
Watch different types of molecules form a solid, liquid, or gas. Add or remove heat and watch the phase change. Change the temperature or volume of a container and see a pressure-temperature diagram respond in real time. Relate the interaction potential to the forces between molecules.

Introduction
PhET States of Matter Simulation Overview
- Core Functionality: Interactive simulation for visualizing molecular behavior across states of matter (solid, liquid, and gas).
- Dynamic Controls: Users can manipulate heat, temperature, and container volume to observe real-time phase changes.
- Data Visualization: Includes a pressure-temperature diagram that updates dynamically based on user inputs.
- Scientific Concepts:
- Molecular bonding and interaction potentials.
- Relationship between intermolecular forces and physical states.
- Thermodynamic principles (pressure, volume, and temperature relationships).
