Gas Laws Demonstrations
Do you have a demonstration for gas laws?
This is a massive request!! There are so many demonstrations of the gas
laws on the Internet it is difficult to make a recommendation without
knowing what aspect of the gas law(s) you wish to demonstrate without
knowing what equipment you have, how long should the demonstration last
and so on. Two of my favorite sources (because of their breadth) are:
but there are hundreds more. There are even "virtual experiments" run on
computer screens with no equipment required, although I think that takes an
important aspect out of experimental measurement.
I have two recommendations regarding your choice:
1. Do not use any mercury thermometers. All mercury thermometers in all
labs -- chemistry, physics, etc. --
all labs should be collected and disposed of properly. Mercury -- used for
so many years in labs -- is extremely toxic and difficult to cleanup if a
thermometer should break.
2. Do not use flammable liquids as a few demonstrations call for.
