Problem 1.1. The Fahrenheit temperature scale is defined so that ice melts at
32°F and water boils at 212°F.
(a) Derive the formulas for converting from Fahrenheit to Celsius and back.
(b) What is absolute zero on the Fahrenheit scale?
Problem 1.2. The Rankine temperature scale (abbreviated °R) uses the same
size degrees as Fahrenheit, but measured up from absolute zero like kelvin (so
Rankine is to Fahrenheit as kelvin is to Celsius). Find the conversion formula
between Rankine and Fahrenheit, and also between Rankine and kelvin. What is
room temperature on the Rankine scale?
Answer the following by filling the blank:
