Webb13 mars 2024 · Brought to you by Sciencing. Go to the last digit of the reading if the thermometer holds steady and constant. In this kind of situation, the last digit will be considered uncertain. If your thermometer reads 36.12 degrees, for example, the uncertainty would be 0.01 degrees, because the last digit (the 2 in 36.12) sets the limit … Webb7 okt. 2016 · Now using your sensitive thermometer your next reading is $107.49$ mK' then the chances are that the actual temperature if fairly close to $105.29$ mK. This is where the type and method of calibration of your thermometer comes in. I have assumed that the reading on your thermometer in the range $103$ mK to $105$ is always about $2.20$ …
