hello there... here you go...
>>>Water and air are abunbant conponents on earth.
>>> Distilled water at standard temperature and pressure has been used as the standard liquid with a reliable specific gravity.
>>>>> Its often a very reliable solvent that most substances would dissolve into, and that might have been another consideration, such as mixing chemical standards for analysis.
>>>Much the same, air's abundant, is fairly a reliable mix of abundant gas elements on earth, and is a reliable gas at standard temperature and pressure for mixing gas standards or conducting experiments.
>>>> But who's to say there might be other liquids or gasses that might be useful for their properties as standards, and react reliably to changes in temperature and pressure.
>>>If you experimentation has to be done at freezing temperatures, water would not be so great as a standard.
