This program covers the important topic of refrigerators in Physics. We begin by discussing how refrigerators are just “heat engines” operated in reverse because they require energy to pump heat away from an object. The entire lesson is taught by working example problems beginning with the easier ones and gradually progressing to the harder problems. Emphasis is placed on giving students confidence in their skills by gradual repetition so that the skills learned in this section are committed to long term memory.
