The temperature changes from 35 degrees Fahrenheit during the night to 75 degrees Fahrenheit during the day. What is the temperature change on the Celsius scale?

A. 72 degrees Celsius
B. 40 degrees Celsius
C. 32 degrees Celsius
D. 22 degrees Celsius

Answer :

The correct answer is: D.) 22 degrees CelsiusThe formula for converting Fahrenheit to Celsius is (°F - 32) x 5/9.



At night, the temperature is 35°F, which is (35-32) x 5/9 = 1.67°C.

During the day, the temperature is 75°F, which is (75-32) x 5/9 = 23.89°C.

The temperature change on the Celsius scale is the difference between the two, which is 23.89°C - 1.67°C = 22.22°C.

So the answer is D.) 22 degrees Celsius.
To find the temperature change on the Celsius scale, first convert the initial and final temperatures from Fahrenheit to Celsius using the formula: Celsius = (Fahrenheit - 32) * 5/9.

Initial temperature in Celsius: (35°F - 32) * 5/9 = 1.67°C
Final temperature in Celsius: (75°F - 32) * 5/9 = 23.89°C

Now, find the temperature change by subtracting the initial temperature from the final temperature:

Temperature change = 23.89°C - 1.67°C = 22.22°C

Rounded to the nearest whole number, the temperature change on the Celsius scale is approximately 22 degrees Celsius. Therefore, the correct answer is:

D.) 22 degrees CelsiusThe formula for converting Fahrenheit to Celsius is (°F - 32) x 5/9.
