Question

The absolute zero temperature in degree Fahrenheit is:

• A. 460
• B. -460
• C. 500
• D. -500

Answer 1

The correct option is B

-460

The absolute zero temperature in Kelvin scale occurs at 0K.

Using temperature conversions,
$\frac{F-32}{9}=\frac{K-273.15}{5}$
$\frac{F-32}{9}=\frac{0-273.15}{5}$
$F=-459.67$

Hence, absolute zero occurs at approximately $-459.67K$.
