This learning resource delves into the concepts of heat, work, and energy, with a specific focus on thermal efficiency. Learners will learn about heat engines, heat pumps, and the principles behind their operation. The lesson plan also covers spontaneous and non-spontaneous processes, culminating in an activity that explores why machines are never 100% efficient. It integrates financial literacy by highlighting the importance of saving and wise spending.
