Well, I've got a project assigned today due in a couple weeks, and it's about finding examples of gas laws in everyday life. I have no idea where to begin looking. I know that everyone is just going to end up using dry ice for everything, but I don't want to do the most obvious things.

So, specifically, I need to find examples of Charles' Law, Boyle's Law, the combined gas law, the ideal gas law, and Avagadro's Law. I understand all of these and can use them all in the work, I just can't think of anything to exemplify these laws in real life.


This being the Pit, I figured at least one or two people could help me out with this.

Thanks, and I'm going to go looking on Wikipedia now...

Bush's law. Gas will rise in price indefinitely.

EDIT - Don't ask the Pit, any examples they tell you will be about farting.

You witness them everywhere. Soda cans, hot-air balloons...

not sure what law it is but the one relating temperature and pressure... think of a propane tank, if heated it will cause higher pressure and eventually explode (that is if they didn't have that wonderful safety valve)

Well, I can just make a video, so I'm sure I can blow something up, provided I find somewhere to do it.

EDIT: Again, I understand the concepts completely to what we have discussed in class, I just want better examples than just the lame and unoriginal stuff.

I forget which law it applies to but as a balloon floats higher the volume in it increases as the air outside gets less dense til it pops

Did this stuff a few months ago. I did Charles' law.What we did was take a syringe, i honestly forget how big (although the pharmacist gave me an odd look when i asked for it). Take the plunger out and seal the other end. Put a marshmellow in it and put the plunger back in. When you push the plunger in, the marshmallow will be crushed by air pressure.

There's another one too. Take the plunger out of another syringe and put a marshmallow in it, then put the plunger back in. Seal the end and when you pull up on the syringe the marshmallow will grow. It's kinda cool.

If I can get my hands on a syringe, I'm doing this, thanks. I still need Boyle's (Volume increases when pressure decreases at a constant temperature), combined gas (the ratio of pressure to the volume constant is constant with temperature), ideal gas (a gas' state is determined by pressure, volume, and temperature as indicated by PV=nRT), and Avogadro's (same volume ideal gases at constant temperature and pressure have an equal number of particles/molocules).

I'm trying to think of some of the other projects.. One was something like heating a tin can with a lid on it until the lid goes flying off. One was putting a ballon over a pop bottle and setting it to different heats.
#13
Okay, this is probably not going to help me (I mean resurrecting this thread), but I now don't need to do the combined gas law, meaning examples for:

Boyle's law
Avogadro's law
ideal gas law

The fizzing of carbonation is pop bottles is caused because the contents on the inside is pressurized, and then starts to equalize itself when you let the cap off.

Or maybe you could site that whole example of crushing a can by heating it up then sticking it in cold water?

Or about how foods boil at diffrent temps based on the pressure? If you lower the pressure enough, you can boil water with your hand.
