Question

If absolute zero is $ -273.15\text{ }{}^\circ C $ on Celsius temperature scale, then the absolute zero on the Fahrenheit scale is

• A. $ -273.15\text{ }{}^\circ F $
• B. $ -\text{ }453.15\text{ }{}^\circ F $
• C. $ -\text{ }459.67\text{ }{}^\circ F $
• D. $ -\text{ }491.67\text{ }{}^\circ F $

Answer 1

Answer: (C)

Celsius and Kelvin scale are related as $ \frac{C}{5}=\frac{F-32}{9} $ or $ \frac{-273.15}{5}=\frac{F-32}{9} $ $ \Rightarrow $ $ F=-459.67\,{{\,}^{o}}F $
