Answer :
Final answer:
The temperature change from 44 degrees Celsius to -56 degrees Celsius is -100 degrees Celsius. When converting a 40.0°F decrease to Celsius, the temperature decreases by approximately 22.2°C.
Explanation:
To calculate the temperature change in degrees Celsius, you subtract the final temperature from the initial temperature. So if the temperature changed from 44 degrees Celsius to -56 degrees Celsius, the temperature change would be:
(-56 °C) - (44 °C) = -100 °C.
Therefore, the correct answer is (a) -100 degrees Celsius.
Conversion from Fahrenheit to Celsius
When there is a decrease in temperature by 40.0°F, the change in degrees Celsius can be found using the conversion formula:
(°F - 32) × 5/9 = °C
For a change in temperature, this becomes:
(°F_change) × 5/9 = °C_change
So for a 40.0°F change:
(40.0°F_change) × 5/9 ≈ 22.2°C_change
Accordingly, the temperature decrease in Celsius for a 40.0°F decrease is about 22.2°C.
