Answer

A $20^{\circ}$ change on the Celsius and Kelvin scale represent the largest change in temperature.

Work Step by Step

A degree unit on the Fahrenheit scale is not a large as a degree unit on the Celsius or Kelvin scales. Therefore, a 20° change in the Celsius or Kelvin temperature would correspond to a larger temperature change than a 20° change in the Fahrenheit scale. The 20° temperature change on the Celsius and Kelvin scales are equal to each other.
