Question

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. What is the difference between these two measurements?.

Answer 1

To find the difference between the two temperatures, we subtract the initial temperature (-17 °C) from the final temperature (-26 °C):

Final temperature - Initial temperature = -26 °C - (-17 °C)

Simplifying this expression, we get:

-26 °C + 17 °C = -9 °C

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