What form the ideal gas law would you use to calculate the temperature of a gas

You can use any form of the Ideal Gas Law, but usually one form is more convenient, depending on the information given.

There are three forms of the Ideal Gas Law.

Form 1

P V = n R T

If the question gives you the number of moles  then

, this is the most convenient one to use.

Form 2

P V = m M R T , where  m  is the mass of the gas and  

M  is its molar mass.

If the question gives you the mass  

m

, this is the most convenient one to use.

Form 3

P  = ρ M R T , where  ρ  is the density of the gas.   If the question gives you the density  

ρ , this is the most convenient one to use.

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.
