What are the four temperatures scales?

• A. Celsius, Kelvin
• B. Fahrenheit, Rankine, Celsius, Kelvin
• C. Rankine, Fahrenheit, Celsius
• D. Fahrenheit, Celsius, Kelvin, Rankine

Answer: (B)

Understanding the common temperature scales used in science and daily life is what this question tests. The four widely used scales are Fahrenheit, Rankine, Celsius, and Kelvin. Kelvin and Rankine are absolute scales, with zero at absolute zero, so they measure thermodynamic temperature directly. Celsius and Fahrenheit are relative scales: Celsius uses 0 at the freezing point of water and 100 at the boiling point at one atmosphere, while Fahrenheit uses 32 at freezing and 212 at boiling. Because these four cover both absolute and everyday temperature concepts, they form the standard set. Listing exactly those four scales is why this option is the best.
