Which value is listed as the absolute zero for the Rankine scale in the material?

• A. 0
• B. -273.15
• C. 459.67
• D. 273.15

Answer: (A)

On the Rankine scale, absolute zero is defined as zero. Rankine uses Fahrenheit-sized degrees, so each increment in Rankine is the same size as a Fahrenheit degree, but the zero point is at absolute zero. That makes 0 Rankine equivalent to -459.67 Fahrenheit (and -273.15 Celsius). The other numbers correspond to absolute zero on other scales or are conversion offsets, not the Rankine zero. In particular, 459.67 is the offset added to Fahrenheit values to get Rankine, not a zero point on Rankine. So the correct value is 0.
