the air temperature at 9am is -5.5 the air temperature at noon is -1.6 what is the temp change during these 3 hours
The temperature change during these 3 hours can be found by subtracting the initial temperature from the final temperature.
Final Temperature: -1.6
Initial Temperature: -5.5
Temperature Change = Final Temperature - Initial Temperature
Temperature Change = -1.6 - (-5.5)
Temperature Change = -1.6 + 5.5
Temperature Change = 3.9 degrees Celsius
Therefore, the temperature change during these 3 hours is 3.9 degrees Celsius.
