When applying Avogadro’s law, the two conditions that must be held constant are temperature and pressure. Avogadro's law states that equal volumes of gases, at the same temperature and pressure, contain an equal number of molecules. Thus, to properly apply the law, both temperature and pressure need to remain constant. Volume and moles may vary as they are directly related to the number of gas particles present.
Which TWO must be held constant when applying Avogadro’s law?
temperature
volume
pressure
moles
