Big Ideas
- Thermal energy always flows from warmer objects to cooler ones in a predictable manner until all substances in a system reach the same temperature.
- Thermal equilibrium is the state in which all parts of a system have reached the same temperature and no more net energy transfer occurs.
Essential Questions
- How does thermal energy move between substances in a system?
- What drives the movement of thermal energy from one object to another?
- What does it mean for a system to reach thermal equilibrium?
- How can we predict when and how thermal equilibrium will occur?
- Why is the flow of thermal energy always from warmer to cooler substances?
