As part of an experiment in the science lab, a thermometer was inserted in a solution in order to measure the temperature over time. At 9:15 a.m. the temperature was –17 °C, and at 11:30 a.m. it was –26 °C.

Question

What is the difference between these two measurements?

A.
8 °C

B.
9 °C

C.
11 °C

D.
43 °C

Answer 1

The difference between these two measurements can be found by subtracting the initial temperature from the final temperature.

Final Temperature - Initial Temperature = Difference

(-26 °C) - (-17 °C) = -26 °C + 17 °C = -9 °C

Therefore, the difference between the two measurements is 9 °C, so the answer is B. 9 °C.

Answer 2

so whats the answer

Answer 3

The answer is B. 9 °C.
