Check the complete question attached.
We have the equation
equation (1); solving for F we get:
equation (2)
I. To check this we are going to use equation (1) to see what hapen when temperature rises from 32 Fahrenheit to 33 Fahrenheit:
For 32 Fahrenheit:
For 33 Fahrenheit:
Now we are going to subtract the two temperatures in degrees Celsius:
As you can see, the temperature increased
degree Celsius.
We can conclude that a temperature increase of 1 degree Fahrenheit is equivalent to a temperature increase of
degree Celsius.
II. To check this one we are going to use equation (2) to see what happens when temperature raises from 1 degree Celsius to 2 degrees Celsius:
For 1 degree Celsius:
For 2 degrees Celsius:
Now we are going to subtract the two temperatures in Fahrenheit:
As you can see, the temperature increased 1.8 Fahrenheit.
We can conclude that a temperature increase of 1 degree Celsius is equivalent to a temperature increase of 1.8 Fahrenheit.
III. Since a temperature increase of 1 degree Fahrenheit is equivalent to a temperature increase of
degree Celsius, we can conclude that this one is false.
The correct answer is D) I and II only
