About States of Matter
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.
How to play States of Matter
Everything is hands-on: drag, click and experiment — the simulation reacts instantly. Watch different types of molecules form a solid, liquid, or gas.
Questions & answers
- What is States of Matter?
- States of Matter is a free interactive simulation from PhET Interactive Simulations (University of Colorado Boulder) that you can play right in your browser on crumble.lol — no downloads and no sign-up. Watch different types of molecules form a solid, liquid, or gas. Add or remove heat and watch the phase change.
- What can kids learn from States of Matter?
- It helps kids explore: describe a molecular model for solids, liquids, and gases. extend this model to phase changes. describe how heating or cooling changes the behavior of the molecules. describe how changing the volume can affect temperature, pressure, and state. relate a pressure-temperature diagram to the behavior of molecules. interpret graphs of interatomic potential. describe how forces on atoms relate to the interaction potential. describe the physical meaning of the parameters in the lennard-jones potential, and how this relates to the molecule behavior.
- What age is States of Matter good for?
- It is designed for high school up to university, and curious kids outside that range can absolutely enjoy poking around it too.
