a

Complete the table of values:

Water Temperature (°C) | $-3$−3 | $-2$−2 | $-1$−1 | $0$0 | $1$1 | $2$2 | $3$3 |
---|---|---|---|---|---|---|---|

Surface Air Temperature (°C) | $\editable{}$ | $\editable{}$ | $\editable{}$ | $\editable{}$ | $\editable{}$ | $\editable{}$ | $\editable{}$ |

b

Continue the pattern in the table to determine the surface air temperature when the water temperature is $4$4 °C.

c

What would be the surface air temperature when the water temperature is $14$14 °C?
