Answer
$70K$
Work Step by Step
The change of temperature in $^{\circ}C$ is the same in $K$
$\Delta T(^{\circ}C) = T_2(^{\circ}C) - T_1(^{\circ}C)$
$T(K) = T(^{\circ}C) + 273$
$ \Delta T(K) = (T_2(^{\circ}C) + 273) - (T_1(^{\circ}C) + 273)$
$ \Delta T(K) = T_2(^{\circ}C) - T_1(^{\circ}C) = \Delta T(^{\circ}C) $
$\Delta T(^{\circ}C) = \Delta T(K) = 70K$
