Rank the size of a change in temperature of one degree fahrenheit, one degree celsius, and one kelvin. in other words, if a thermometer were to show that the temperature outside increased by these amounts, which change would feel the largest? if any of the options are the same magnitude, stack them above one another. rank the sizes of one degree in each scale from largest to smallest. to rank items as equivalent, overlap them.

Kelvin = C + 273.15
Kelvin and Celsius will be ranked the same because the temperature change is the same. Kelvin is just set at a different zero point.

Fahrenheit has the largest range which you can see by the freezing (32F) and boiling (212F) point of water. (212-32 = 180) Whereas the temperature change going from freezing to boiling water for both Kelvin and Celsius is 100. This means that one degree Fahrenheit feels smaller and should be ranked least.
