12. The freezing point of water is the reference (zero) point for the Celsius scale. At the freezing point of water, what number of Fahrenheit degrees must be subtracted from the temperature so that it will also be the zero point? 13. So, to convert from \( { }^{\circ} \mathrm{F} \) to \( { }^{\circ} \mathrm{C} \), two adjustments are needed. One has to subtract 32 to get to the same reference point \( \left(0^{\circ} \mathrm{C}\right) \), and then use a conversion factor (see CTQ 11). Using only your answers to CTQ 11 and 12 , complete the equation below. \[ { }^{\circ} \mathrm{C}=\left({ }^{\circ} \mathrm{F}-\quad\right) \times\left(\frac{\mathrm{C}^{\circ}}{\mathrm{F}^{\circ}}\right) \] 14. To convert \( { }^{\circ} \mathrm{C} \) to \( { }^{\circ} \mathrm{F} \), one has to use the conversion factor to convert to \( { }^{\circ} \mathrm{F} \) first, and then add \( 322^{\circ} \mathrm{F} \) units ("adding apples to apples"). Write an equation for this. \[ { }^{\circ} \mathrm{F}= \] 15. Some textbooks give the ratio \( 9 / 5 \) as the conversion factor between \( { }^{\circ} \mathrm{F} \) and \( { }^{\circ} \mathrm{C} \). As a team, develop an explanation of how this is the same as the one in the equation you developed in CTQ \( 14 . \) 16.
