Heat Engine/Gas Law Apparatus

Product Code: TD-8572A

Description

The Heat Engine and Gas Law Apparatus enables students to perform quantitative Ideal Gas Law experiments, while exploring a functional heat engine. A Rotary Motion Sensor and Pressure Sensor can be added to graph heat engine cycles, determine actual efficiency, and more!


Features

  • Air chamber can be immersed in hot or cold water
  • Two ports for connecting the air chamber tubing or a Low Pressure Sensor
  • Ultra-low friction graphite piston
  • Millimeter scale measures piston displacement
  • Locking screw secures piston for fixed volumes
  • Precision-bore Pyrex cylinder with protective plastic shield
  • Two port shut-off valves
  • Rod clamp for mounting to rods or stands

Applications

  • Pascal’s Principle
  • Heat Engine Cycles
  • Charles’ Law Experiment
  • Combined Gas Law Experiment (Gay-Lussac’s)
  • The Mass Lifting Heat Engine Experiment
  • Add a mass to the platform for work experiments

How It Works

Heat Engine Cycle:

  1. 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.
  2. The heat engine cycle is plotted in real time using a Pressure vs. Volume graph.
  3. 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.
  4. 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.
