Final answer:
The temperature decrease from Fahrenheit to Celsius can be calculated using the formula ΔT(°C) = (ΔT(°F) - 32) × 5/9. For a decrease of 40.0°F, the temperature decreases by approximately 4.44°C.
Step-by-step explanation:
The temperature decrease can be calculated using the formula:
ΔT(°C) = (ΔT(°F) - 32) × 5/9
For a decrease of 40.0°F, the temperature decrease in Celsius would be:
ΔT(°C) = (40.0 - 32) × 5/9 = 8 × 5/9 ≈ 4.44°C
This shows that any change in temperature in Fahrenheit degrees is approximately nine-fifths the change in Celsius degrees
