a.

Answer to Problem 98E
The relationship between degree Celsius C and Fahrenheit F is
Explanation of Solution
Given:
Water freezes at
Formula/ concept used:
The temperature on Celsius and Fahrenheit scales is shown in Figure-1.
Calculations:
Let C and F be the same temperature on the Celsius and Fahrenheit scales respectively.
The linear characteristics of the Celsius scale is
Two scales will be identical when linear characteristics of both scales is same, i.e.,
This is the relationship between degree Celsius C and Fahrenheit F .
Conclusion:
The relationship between degree Celsius C and Fahrenheit F is
