Big Ideas
- Matter changes its state, temperature, and particle motion when thermal energy is transferred.
- Models help us understand and predict the physical changes that occur in pure substances during heating or cooling.
Essential Questions
- How does adding or removing thermal energy affect a pure substance’s state of matter?
- Why does the motion of particles change when the temperature of a substance changes?
- How can a model show the relationship between thermal energy and the states of matter?
- What happens to particle movement during phase changes such as melting, freezing, evaporation, and condensation?
- How does understanding thermal energy transfer help us predict changes in matter?
