How It Works
Heat Engine Cycle:
- When the air chamber is moved from the cold water bath to the hot bath, the piston rises, lifting the 200 g mass to demonstrate work. The mass is removed, and the air chamber is returned to the cold bath, closing the isobaric/isothermal cycle.
- The heat engine cycle is plotted in real time using a Pressure vs. Volume graph.
- Pressure in the cylinder is measured by a pressure sensor. Volume is measured by tracking the piston’s position with a rotary motion or motion sensor. Temperatures of the hot and cold baths are recorded using temperature sensors.
- Students compare the area inside the P-V cycle to the actual work done while lifting the weight to determine how the efficiency of their heat engine compares to the theoretical maximum.
