Question

Find the reading on the Fahrenheit' and Rankine scale corresponding to
absolute zero.
​

Answer 1

relation between Fahrenheit , Rankine and Kelvin scale is....

(F - 32)/180 = (R - 491.67)/180 = (K - 273.15)/100

we know, absolute zero means , Temperature in Kelvin is zero.

so, K = 0

then, (F - 32)/180 = (R - 492)/180 = -273.15/100

or, (F - 32)/180 = -273.15/100 = -2.7315

or, F - 32 = -180 × 2.7315

or, F = 32 - 180 × 2.7315

or, F = -459.67

hence, reading on the Fahrenheit scale is -459.67°F

again, (R - 491.67)/180 = -273/100

or, R - 491.67 = -180 × 273/100 = -491.67

or, R = 0

hence, reading on Rankine scale is 0°R.

Answer 2

Answer:

The Rankine scale is similar to the Kelvin scale in that zero is Absolute Zero; however, a degree Rankine is defined as equal to one degree Fahrenheit as opposed to one degree Celsius (as used by the Kelvin scale). A temperature of -459.67 F is equal to 0 R.
