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.

Use cases

  • High school students studying thermodynamics and heat engines
  • Teachers demonstrating heat efficiency concepts in class
  • Learners practicing heat, work, and temperature calculations
  • Students exploring P–V diagrams and cyclic processes

Features

  • Adjust heat input and work to calculate efficiency and rejected heat
  • Explore maximum efficiency from hot and cold reservoir temperatures
  • Change volume and pressure differences to control P–V loop area
  • Switch between clockwise engine and counterclockwise refrigerator cycles
  • Complete guided missions covering efficiency, temperature limits, and cyclic work
