7. Recent communication with the inhabitants of Neptune have revealed that they have a Celsius- ype temperature scale, but based on the melting point (0°N) and boiling point (100°N) of their most common substance, hydrogen, Further communications have revealed that the Neptunians know about the perfect gas behavior, and they find that in the limit of zero pressure, the value of oV is 28 dm 3 atm at 0°N and 40 dm 3 atm at 100°N. What is the value of absolute zero of emperature on their temperature scale?
