1. The problem statement, all variables and given/known data Jack decides to create his own temperature scale. He places an uncalibrated mercury thermometer into an ice-water bath and records the mercury level as 20.0S. He then places the same thermometer above boiling water and records the mercury level as 170S. Finally, he divides the distance between these two levels into 150 equal lengths. Calculate the reading on a Celsius thermometer when Jack's thermometer reads 95S. 2. Relevant equations I used temperature, T = (xT - x0)/(x100 - x0) x 100. 3. The attempt at a solution My answer is 50C. But the correct answer is 75C. Can anyone kindly help please?
