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.

The size of a change in temperature of one degree on the Fahrenheit, Celsius, and Kelvin scales can be ranked by comparing the magnitude of their degree units:

• One degree Celsius (°C) and one kelvin (K) represent the same size of temperature change. This is because the Kelvin scale is defined to have the same magnitude per unit as the Celsius scale, differing only by an offset of 273.15 (i.e., 1 K=1 °C1,K=1,°C1K=1°C in terms of magnitude of change)

• One degree Fahrenheit (°F) is smaller than one degree Celsius or one kelvin. Specifically, 1 degree Celsius equals 1.8 degrees Fahrenheit, meaning a 1°F change corresponds to a smaller temperature change than 1°C or 1 K

Ranking from largest to smallest temperature change:

1. One degree Celsius (°C)
2. One kelvin (K)
3. One degree Fahrenheit (°F)

Thus, if a thermometer showed an increase of 1°C, 1 K, and 1°F, the changes of 1°C and 1 K would feel equally large and larger than the change of 1°F. The Fahrenheit change would feel the smallest.
