Question

Which of the following temperature scales has the smallest unit interval?

A.Celsius
B.Kelvin
C.Fahrenheit
D.Calorie

Answer 1

The smallest unit interval is in the Fahrenheit scale

Explanation:

For the conversion between Celsius and Fahrenheit:

Δ1°C=Δ1.8°FΔ1°C=Δ1.8°F

For the conversion between Kelvin and Celsius:

Δ1K=Δ1°CΔ1K=Δ1°C

Thus, a 1-degree change in Celsius is equivalent to a 1.8-degree change in Fahrenheit, which means the Fahrenheit scale has smaller intervals than the Celsius or Kelvin scales.

The correct answer is C. Fahrenheit.
