4B70.36 - Adiabatic Gas Law - Compress Butane | Instructional Resources and Lecture Demonstrations

Fill the syringe with butane from the refill cartridge.

uickly cover the tip so that the butane does not escape and place the tip onto the rubber foot pad.

Compress the gas in the syringe and observe it turn to a liquid at the bottom of the syringe.

Code Number:

4B70.36

Demo Title:

Adiabatic Gas Law - Compress Butane

Condition:

Excellent

Principle:

Adiabatic expansion and compression

Area of Study:

Heat & Fluids

Disclaimer

Equipment:

Butane refill cartridge, 60 cc syringe, rubber feet cushions.

Procedure:

NOTE: This demonstration is best done in a small class where the students can come and observe the syringe compression directly.

Fill the syringe with butane from the refill cartridge. Quickly cover the tip so that the butane does not escape and place the tip onto the rubber foot pad. Compress the gas in the syringe and observe it turn to a liquid at the bottom of the syringe.
