Question

The drawing shows two thermometers, A and B, whose temperatures are measured in °A and °B. The ice and boiling points of water are also indicated. (a) Using the data in the drawing, determine the number of B degrees on the B scale that correspond to 1 °A on the A scale. (b) If the temperature of a substance reads +44.0 °A on the A scale, what would that temperature read on the B scale?

I've worked out that part A) is 1.22 degrees, but for the life of me I can't work out how to solve B).

Answer 1

@TipsieOver , you know that 60 degrees A equals 130 degrees B. You also know that for every degree in A, you add 1.22 degrees in B. Now using that logic, you know that 44 degrees in A is 16 degrees away from 60. Therefore, you multiply 16 by 1.22, and subtract that from 130 for your temperature in B. Make sense? :)

Answer 2

@Khushal_Shah - thanks for your reply. I tried it the way you explained on a tutorial problem and the answer was still incorrect. In the tutorial problem the only difference is that instead of 44 degrees A it's 40 degrees A. My answer was 105.6 but apparently the correct answer is 105.4 (and the tolerance is only plus or minus 0.1 in the fourth sig. fig.). I tried using 110/90 instead of 1.22 but it was still out. With temp conversions from Celsius to Fahrenheit I'm aware that you multiply by 9/5 and then add 32 degrees (the ice point) so I was wondering if the ice point was relevant in this question - still can't get it to work though. Tearing my hair out now.
