What are the two key concepts for this section? What is energy ? Define and distinguish between kinetic energy and potential energy and give an example of each. What is heat (thermal energy) ? Define and give two examples of electromagnetic radiation. What is energy quality ? Distinguish between high-quality energy and low-quality energy and give an example of each. What is the first law of thermodynamics (law of conservation of energy) and why is it important? What is the second law of thermodynamics and why is it important? Explain why the second law means that we can never recycle or reuse high-quality energy.
