Question

(1)You work in a materials testing lab and your boss tells you to increase the temperature of a sample by 45.2 ∘C . The only thermometer you can find at your workbench reads in degrees Fahrenheit. Part A If the initial temperature of the sample is 66.8 ∘F, what is its temperature in degrees Fahrenheit when the desired temperature increase has been achieved?

(2)

Like the Kelvin scale, the Rankine scale is an absolute temperature scale: Absolute zero is zero degrees Rankine (0∘R∘R). However, the units of this scale are the same size as those on the Fahrenheit scale (∘F∘F) rather than the Celsius scale (∘C∘C).

Part A Given that water at standard pressure freezes at 0∘C∘C, which corresponds to 32∘F∘F, and that it boils at 100∘C∘C, which corresponds to 212∘F∘F, calculate the temperature difference ΔTΔT in degrees Fahrenheit that corresponds to a temperature difference of 1 KK on the Kelvin scale.

(3) In an alcohol-in-glass thermometer, the alcohol column has length 12.49 cmcm at 0.0 ∘C∘C and length 22.35 cmcm at 100.0 ∘C∘C. What is the temperature if the column has length 18.32 cmcm ?
