Temperature differences on the Rankine scale are identical to differences on the Fahrenheit scale, but absolute zero is given as 0°R. (a) Find a relationship converting the temperatures TF of the Fahrenheit scale to the corresponding temperatures TR of the Rankine scale. TR = (b) Find a second relationship converting temperatures TR of the Rankine scale to the temperatures TK of the Kelvin scale. TK =
