The absolute zero pressure can be attained at a temperature of

A 0°C
B -273°C
C 273 K
D None of these

Correct Answer: -273°C

Correct Option is (B)
The lower the temperature, the lower the pressure inside of the sphere.
If the exact values were plotted out, a linear relationship would be apparent.
Extrapolating this line to the point where there would be no pressure yields absolute zero, which is about -273.15 degrees Celsius.
