Title: 3RD PERIOD
Course: 2024 Physics 3

In Unit 4, students will continue to investigate what they cannot see by examining heat, temperature, and thermal energy in practical contexts such as heat engines, heat pumps, and refrigerators. The focus of this unit is the study of relationships and change, so it’s important that students can discuss—in addition to calculate—what happens when a physical scenario changes, such as the consequences of adding heat to, or removing heat from, a system. Throughout this unit, students will use representations and models (PV diagrams, energy bar charts, or free-body diagrams) to construct evidence-based explanations and help them make predictions and justify claims about new phenomena. These representations and models will also help students develop connections and transfer their learning across disciplinary boundaries so that they are able to link, synthesize, and apply ideas they have learned across the sciences and mathematics. Unit 3 also acquaints students with the second law of thermodynamics, entropy, and how the behavior of complex systems can be modeled with the mathematics of probability.

Topics 4.1 Thermodynamic Systems, 4.2 Pressure, Thermal Equilibrium, and the Ideal Gas Law, 4.3 Thermodynamics and Forces, 4.4 Thermodynamics and Free-Body Diagrams, 4.5 Thermodynamics and Contact Forces, 4.6 Heat and Energy Transfer, 4.7 Probability, Thermal Equilibrium, and Entropy
