The answer is All of the above. The rearranged law incorporates Charles Law about the relationship between the volume and temperature of an ideal gas with Boyles law that stipulates the relationship between pressure and volume of an ideal gas. Avogadro principle strengthens on this formula by applying the standard of the number of atoms in a mole of gas.(P1*V1)/T1 = (P2*V2)/T2
where:
V is the volume P is the pressure T is the temperature measured in kelvin k is a constant (with units of energy divided by temperature)
