Thermal Energy and Molecular Motion

The video tutorial covers Lesson 1.3 on Thermal Energy, Temperature, and Motion. It begins with an introduction and overview of the lesson, followed by detailed instructions on exploring the Thermal Energy Simulation. The tutorial then demonstrates simulating hot and cold water to model the food coloring experiment. Finally, it concludes with a reflection on the lessons learned and a homework assignment on absolute zero.
