Guillaume puts a bottle of soft drink in a refrigerator and leaves it there until its temperature has dropped 15.1 K.

Part A:
What is the magnitude of its temperature change (Change in T = 15.1 K) in degrees Celsius?
15.1 C

Part B:
What is the magnitude of the temperature change (change in T = 15.1 K) in degrees Fahrenheit?

(a) The magnitude of its temperature change in degrees Celsius is .

(b) The magnitude of the temperature change (change in T = 15.1 K) in degrees Fahrenheit is .

Explanation:

(a)  Expression for change in temperature is as follows.

                         = 15.1 K

                    =

                    =

                    =

Therefore, the magnitude of its temperature change in degrees Celsius is .

(b)  Change in temperature from Celsius to Fahrenheit is as follows.

           F = 1.8C + 32

          C =

Since,   K = C + 273

or,    

                      = 1.8 (15.1)

                      =

or,                  =

Thus, we can conclude that the magnitude of the temperature change (change in T = 15.1 K) in degrees Fahrenheit is .
