Ideal gas law. practice question for college entry test-which of the following indicate the ideal gas law?

a) PV=knT or PV=RnT b) V=kT c) PV=k d) KTV=PR and what do the letters stand for-i know p is pressure, v is volume, t-is temperature? and one is planks constant? thanks

The correct answer is a) I usually write this, and see it in other texts as: PV = nRT. There are a number of options available how to use this equation. I use: P = Pressure in kPa ( 1 atmosphere = 101.3kPa) V = volume in litres n = number of moles (not the mass in moles) R = Universal gas constant In my system this is 8.31 T = temperature in K If you look up Gas Constant in Wikipedia you will get all the options that there are for using different values. As far as I know, the system above is fairly common universally.

perfect gasoline regulation basically works on gasses with specific characteristics. the perfect gasoline regulation assumes that the molecules do no longer attrat one yet another, have no mass, and so on. this would not carry actual below specific situations, like at temperatures close to to absolute 0 (the gasoline molecules exhibit appeal at such low temperatures)

PV = nRT in the case of this question the answer is a). Hope this helps. :)

its not d. its not c either. and definitely not b....hmmm. The k is typically boltzman's constant, planck's is denoted by an h or hbar=h/2pi. The n should really be N because n=N/V is concentration
