i need any gas law experiment(boyle's, dalton's, gay-lussac's,charles',ideal,combined,avogadro's) i don't need their definitions, i just need experiments explaining at least one of them. THANKS!!! :D

When I was a general chemistry TA, the students did an ideal gas law experiment to measure the molecular weight of a gas (butane).
You take a butane lighter, attach a tube to it and run it into an upside-down graduated cylinder fille with water sitting in a basin of water. As you empty the lighter, the gas filled in the graduated cylinder, and you can measure the volume. Pressure and temperature can be provided by the instructor, or measured if the lab has a thermometer and barometer.
P,V, and T are known, so you solve for n. By weighing the lighter befoe and after, you can related n to molecular mass.
As a bonus, Dalton's law is also included, as the pressure of the butane is actually atmospheric pressure minus the vapor pressure of water.

the first man or woman to respond to is pointing you contained in the right route, yet a touch extra is easily occurring. The can become packed with water vapor, no longer air. So the outcome become no longer via air contracting, yet to water re-condensing. the quantity replace for the 2d procedure (water) is much better than for the first procedure (air). even as the quantity of the textile contained in the can were given smaller, the rigidity on the outdoors of the can brought with reference to the can to give way.

I wish I had my STAWA book to help you...because I did some experiments on that stuff *sigh*
