Explanation:

Step1: Recall temperature - change formula

The temperature change is calculated by subtracting the temperature at sunrise from the temperature at sunset. Let $T_{s - r}$ be the temperature at sunrise and $T_{s - s}$ be the temperature at sunset. The temperature - change formula is $\Delta T=T_{s - s}-T_{s - r}$.

Step2: Calculate temperature change for Day 2

For Day 2, $T_{s - r}=-8.25^{\circ}C$ and $T_{s - s}=29.21^{\circ}C$. Then $\Delta T = 29.21-(-8.25)$.
Using the rule $a-(-b)=a + b$, we have $\Delta T=29.21 + 8.25$.
$29.21+8.25 = 37.46^{\circ}C$.

Answer:

$37.46$
