c) one degree Farenheit
Explanationto solve this let's convert 1° C into kelvin and Celsiuts, then,let's compare
Step 1
a) convert 1 °C into Kelvin:
to do that, we need to use the formula
[tex]\begin{gathered} °K=C+237\text{ \degree} \\ replace \\ °K=1\text{ +237\degree} \\ °K=238°\text{ K} \end{gathered}[/tex]hence
[tex]1\text{ \degree C=238 K}[/tex]so, one degree Kelvin is smaller than aone degree celsius ( note that 1° C= 238 °K)
Step 2
now, let's convert 1° C into Farenheit
we need to use the formula:
[tex]\begin{gathered} °F=1.8\text{ C+32} \\ where\text{ C is the measure in \degree C} \end{gathered}[/tex]replace and calculate
[tex]\begin{gathered} \begin{equation*} °F=1.8\text{ C+32} \end{equation*} \\ °F=(1.8*1)+32=33.8 \\ °F=33.8\text{ \degree F} \end{gathered}[/tex]so
[tex]1\text{ \degree C=38.3 \degree F}[/tex]so, one degree Fahrenheit is smaller than aone degree celsius ( note that 1° C= 38.3 °F)
Step 3
finally, compare °F and °K
[tex]\begin{gathered} 1\text{ \degree C=238 \degree K=38.3 \degree F} \\ 238°K=38.3°F \\ F=\frac{238}{38.3}K \\ F=6.21\text{ \degree K} \end{gathered}[/tex]so, the measure in °F is six times the measure in °K
therefore,
the smaller unit is
c) one degree Fahrenheit
