Problem: I need to find the new pressure inside a combustion chamber, from the burning of the fuel, and the increase in temperature, if the piston/plunger seized/
some of this is nominal, just to get a general idea of where I'm at.
Honestly it's best explained as a pipe bomb... what if i have a set volume cylinder, that has some propane with some room air in it.. somehow the propane reacts, then the pipe is thrown into a camp fire (oh no!) and the gas is heated via the cylinder to a relatively hot temp, what is the new pressure inside?
I believe, I can use PV=nRT, however because of some insecurities about what actually creates the pressure difference when something burns.. I don't know how to set it up... like, when something burns is there more moles on the new side of the eqn if there is a larger sum of coefficients in the balanced eqn? .. or is it just the actually temp change of the gas that causes it to expand.
also, why is butane more "volatile of and explosion" over propane?
hope that makes sense.. and I'm not making a pipe bomb.. or any intentional weapon for that matter..
Thanks,
K
