The Rankine scale. Named after William John Macquorn Rankine (a Scottish engineer and physicist who proposed it in 1859), the Rankine scale is similar to the Kelvin scale in that the zero point is placed at absolute zero, but the size of temperature differences are the same as that of the Fahrenheit scale (e.g., a change in temperature of 1°F corresponds to a change of 1°R). 

(a) Determine the conversion formula to go from the Fahrenheit to the Rankine scale. 

(b) Find the formula to convert from Kelvin to Rankine.

(c) What is the temperature of the freezing point of water on the Rankine scale? What is room temperature on this scale?
