For instance, a 3' pipe, with 2" ID has 1.302 PSI at the base. Does a 3' tall chamber, with a 12" ID on top and 2" ID at the base still only have 1.302 PSI? Does the added volume have no effect?

The 1st Postulate, namely that "a line may be drawn between any two points", leads directly to Zeno's Paradox, that motion would be impossible. It also allows the construction that results in the Pythagorean Theorem which leads to the need to create the irrational numbers.

My children are fascinated with meteors, although they have not witnessed them personally. I want to find out when the biggest ones are predicted for my area, but I don't know where to find the information. Can anyone suggest some good websites that I can visit to get a schedule of predicted meteor showers? I would love to watch some with my kids. -Thanks in advance-

whats the diff between heat of combustion and heat of formation?
when calculating, which one do i have to use products minus reactants?

ex.
if the problems tells you that the reaction of burning methane has produced say like 500 kJ...then would that be heat of combustion? except you negate it?
