Gas Laws

1. Which Gas Law was demonstrated in the KZbin video with the "Happy Birthday" balloon and the heat gun? Charles' Law- Volume and Temperature

Balloon inflation- i dont think pressure inside is same as outside, otherwise on opening the mouth of inflated balloon air wont come out and it would stay inflated. Pressure of air inside is more than air outside; it is the pressure of stretched rubber that balances the excess pressure inside.

If you have a moment, could you take a look at kzbin.info/www/bejne/gYHRY5KOipmofZo ? This video uses your demonstration to make a case for relative density accounting for what the world at large generally calls 'gravity.' I commented as Johnny Ragadoo (a ragadoo is an old sailor's term for an oilskin coat), and would be fascinated to hear if I made any errors in fact or physics. My post begins with "SW, your passion is admirable. May I offer what I hope is some illumination?" I imagine SW's use of your production amounts to fair use. Your insight on SW's relative density hypothesis would be very interesting. To answer Sleeping Warrior's question below, gas expands with two limitations I can think of. A container will halt its expansion (assuming the container isn't permeable), and just as water will slosh in a bucket, gas will conform to force applied to it. So, yes, you can have gas pressure without a container. You can even have gas pressure without a containing force, until equilibrium is asserted, discounting the gravitational forces from each gas molecule (or atom). Which, of course, in the case of some gas clouds, you can't do. Jupiter comes to mind.
