Heat Engines & Efficiency
by Anonymous
Calculate efficiency from heat in and work done, then explore the limit set by two reservoir temperatures and the area of a P–V loop.
About this app
Heat Engines and Efficiency is an interactive physics learning app for exploring how heat input, work, and rejected heat are related. Adjust the heat received and work done to calculate efficiency, compare the maximum efficiency set by hot- and cold-source temperatures, and examine how the area and direction of a P–V cycle represent work and distinguish an engine from a refrigerator. Guided missions provide practice with the key relationships.
