Answer
$T_2>T_3>T_1$
Work Step by Step
We can convert $T_1$ to degrees Celsius.
$C = K - 273$
$C = 0 - 273$
$C = -273$
$T_1 = -273^{\circ}C$
We can convert $T_3$ to degrees Celsius.
$C = \frac{5}{9}(F-32)$
$C = \frac{5}{9}(0-32)$
$C = -18$
$T_3 = -18^{\circ}C$
We can rank the three temperatures from highest to lowest:
$ 0^{\circ}C> -18^{\circ}C> -273^{\circ}C$
$T_2>T_3>T_1$
