4F10.25 - Maxwell's Demon
|
|
![]() |
Code Number: 4F10.25
Demo Title: Maxwell's Demon
Condition: Good
Principle: Entropy
Area of Study: Thermodynamics
Equipment:
Computer programs and on-line applets, Vortex tube, digital thermometers, compressed air hose.
Procedure:
There are many programs, applets, apps, and screen savers that will simulate a Maxwell's Demon situation. Choose the appropriate program or applet for your presentation.
The vortex tube is a commercial model designed for machinist type work. With the air pressure we have available in our Lecture Rooms a 50 degree C temperature difference is easily achievable.
The Jack-in-the-Box can be used as a humorous model to explain Maxwell's demon.
