Question

If absolute zero is -273. 15${}^{\circ }$C on Celsius temperature scale, then the absolute zero on the Fahrenheit scale is

• A. -227.15${}^{\circ }$F
• B. -453.15${}^{\circ }$F
• C. -459.67${}^{\circ }$ F
• D. -49l.67${}^{\circ }$F

Answer 1

Answer: (C)

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