Comprehension II
Recent communications with the inhabitants of Neptune have revealed that they have a Celsius type temperature scale,
\( \mathrm{P} \) but it is based on the melting point \( \left(0^{\circ} \mathrm{N}\right) \) and boiling point \( \left(100^{\circ} \mathrm{N}\right) \) of their most common substance, hydrogen. Further communications have revealed that the Neptunians know about perfect gas behaviour and that they find in the limit of W zero pressure, the value of \( P V_{\mathrm{m}} \) is \( 28 \mathrm{~L} \) - atm at \( 0^{\circ} \mathrm{N} \) and \( 40 \mathrm{~L}-\mathrm{atm} \) at \( 100^{\circ} \mathrm{N} \).
What is the value of the absolute zero of temperature on their temperature scale?
(a) \( 233.33^{\circ} \mathrm{C} \)
(b) \( -233.33^{\circ} \mathrm{C} \)
(c) \( -233.33^{\circ} \mathrm{N} \)
(d) \( 233.33^{\circ} \mathrm{N} \)
