Physics: temperature

Question

Using the correct relationship between temperature in Celsius and Fahrenheit, what one temperature has the Fahrenheit value equal the Celsius value?

Answer 1

C= (5/9)(F - 32)

 

Let's replace F with C

 

C = (5/9)(C - 32)

 

(9/5)C = C - 32

 

(4/5)C = - 32

 

C = -40

 

When the Celsius temperature is -40 degrees, it's corresponding Fahrenheit temperature is -40 degrees.
