Answer:

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:
#color(blue)11,12,17,19,23,27,color(red)31#

#color(blue)11# is our lowest number and #color(red)31# is our highest number.

#"highest number" - "lowest number" = "range"#
#color(red)31 - color(blue)11 = "range"#
#20 = "range"#
