Explanation:

Step1: Recall temperature - change formula

The temperature change $\Delta T$ is given by the formula $\Delta T=T_{sunset}-T_{sunrise}$.

Step2: Calculate temperature change for Day 1

For Day 1, $T_{sunrise}=- 13.38^{\circ}C$ and $T_{sunset}=17.09^{\circ}C$. So, $\Delta T_1=17.09-(-13.38)$. Using the rule $a - (-b)=a + b$, we have $\Delta T_1=17.09 + 13.38=30.47^{\circ}C$.

Step3: Calculate temperature change for Day 2

For Day 2, $T_{sunrise}=-9.44^{\circ}C$ and $T_{sunset}=22.03^{\circ}C$. So, $\Delta T_2=22.03-(-9.44)=22.03 + 9.44 = 31.47^{\circ}C$.

Step4: Compare the temperature - changes

Since $30.47^{\circ}C<31.47^{\circ}C$, the temperature change was most on Day 2.

Answer:

The temperature change on Day 1 was $30.47^{\circ}C$. The temperature change was most on Day 2.
