4B70.30 - Adiabatic Gas Law Apparatus - Pasco

See paragraph one in the procedure section
Code Number:
Demo Title:
Adiabatic Gas Law Apparatus - Pasco
Adiabatic Expansion and Compression, Carnot Cycle
Area of Study:
Heat & Fluids
Pasco adiabatic expansion apparatus, interface, and laptop computer.

Plug the pressure, temperature, and volume sensors into the right ports of the interface.  The adiabatic templates are saved in the computer so its just a matter of bringing them up and turning on the apparatus.
