Physics Digital Textbook
Thermal Physics · Chapter

Thermal Physics

Connect particle motion, temperature, heat transfer, thermal properties, and changes of state.

Start chapter Next: Waves

Learning Path

Checkpoint 1: particles

particles

Study two or three interactives, then answer the concept checks before moving on.

Checkpoint 2: transfer

transfer

Study two or three interactives, then answer the concept checks before moving on.

Checkpoint 3: properties

properties

Study two or three interactives, then answer the concept checks before moving on.

Adaptive Suggestion

If this chapter feels hard, study the first few interactives and use the concept checks until your streak improves. If it feels easy, jump to resources with videos or OSPSG links and explain the model evidence in your own words.
