ecent communication with the inhabitants of Neptune has revealed that they have a Celsius-type temperature scale, but based on the melting point (0oN) and boiling point (100oN) of their most common substance, hydrogen. Further communications have revealed that the Neptunians know about perfect gas behavior and they find that, in the limit of zero pressure, the value of pV is 28 dm3atm at 0oN and 40 dm3atm at 100oN. What is the value of the absolute zero of temperature on their temperature scale
