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

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

Answer: (B)

Absolute zero is the lowest possible temperature, where molecular motion effectively stops. On the Fahrenheit scale, that limit is -459.67 degrees. This comes from how Fahrenheit relates to the Rankine scale, which is an absolute temperature scale with zero at absolute zero. Since Fahrenheit temp equals Rankine temp minus 459.67, when Rankine is zero, Fahrenheit is -459.67. The other numbers aren’t absolute zero: 0 F is just a particular low temperature well above the absolute limit, 273.15 is a Kelvin value that corresponds to 32 F, and 459.67 without a negative sign is not the absolute zero on Fahrenheit.
