[edit] Constant

I'm not sure whether or not it matters, but isn't 'k' generally used as a constant rather than 'r'? Just asking since the other gas law articles use 'k'. Hey jude, don't let me down 22:27, 1 March 2007 (UTC)

Generally, yes, the constant would be represented by k. However, this is a unique constant known as the ideal gas constant, which is important enough to recieve its own letter (r). 75.40.94.244 (talk) 15:26, 31 May 2008 (UTC)

[edit] Avogadro's Law

I seem to remember combined Avogadro's Law with the other three gas laws to produce a slightly different combined gas law that incorporated the number of moles of gas - this way, if the mass of gas was not constant, the law would still hold true. (Something like: PV/nT = k, thus P1V1/n1T1 = P2V2/n2T2). Is this just me or is it commonly accepted? 75.40.94.244 (talk) 15:29, 31 May 2008 (UTC)

You are thinking about the ideal gas law (PV=nRT), the combined gas law only focuses on the pressure, volume, and temperature of a given gas sample. —Preceding unsigned comment added by 70.130.175.19 (talk) 19:26, 1 June 2008 (UTC)
