Expert Solution
Step 1

A) The lowest and the highest temperature recorded in Fahrenheit scale is given as TL = 68oF and TH=158oF.

Required:

The equivalent Celcius temperature i.e. (TL)oC and (TH)oC are required:

The relation between the Celsius and the Fahrenheit scale is given as follows:

ToC= ToF-32×59
