The range is $20$

#### Explanation:

First of all, the range is the difference between the highest number and the lowest number in a given group of numbers. Here is our group. I got rid of °C so that it's easier to see the numbers:

$27 , 12 , 31 , 19 , 23 , 11 , 17$

Let's put them in order from lowest to highest:
$\textcolor{b l u e}{11} , 12 , 17 , 19 , 23 , 27 , \textcolor{red}{31}$

$\textcolor{b l u e}{11}$ is our lowest number and $\textcolor{red}{31}$ is our highest number.

$\text{highest number" - "lowest number" = "range}$
$\textcolor{red}{31} - \textcolor{b l u e}{11} = \text{range}$
$20 = \text{range}$
