a question about uncertainties?

Question

"A thermometer gives a reading of 96.1F+0.2F. What is the temerature in C? What is the uncertainty?"

What's an uncertainty and how do you figure it out?
Pleaaaseeee help!

Answer 1

The uncertainty is a percent value that could be off from the real value. So the uncertainty here is 0.2F, giving an uncertainty value of 0.2081%

First convert 96.1 to Celcius: 35.61

Then convert 96.3 to Celcius: 35.72

Then subtract: 0.11C

So if your uncertainty in degrees F is 0.2, then in degrees C it is 0.11

Answer 2

uncertainty in the measurement. if you look at a thermometer, you can't give the temperature to arbitrary precision, maybe the scale is marked every 0.5 F and your eyes can possibly estimate to the nearest half mark. the uncertainty in this measurement is +/- 0.2 F, meaning the true value is estimated to be in the range 95.9 ... 96.3 F.

convert to degrees C according to C = (F - 32)*5/9.

convert the uncertainty by multiplying the fahrenheit uncertainty by 5/9 (35.61 +/- 0.11). sometimes the uncertainty is rounded to just one significant figure, as in 35.6 +/- 0.1.

Answer 3

To convert a temperature to Celsius here's the formula:
C=(F-32)0.555
With the C meaning Celsius and the F meaning Farenheit.
So you would substitute The F for 96.1.
C=(96.1-32)0.555
Then you would subtract 32 from 96.1 and you'll get 64.1
C=(64.1)0.555
After that, you'll multiply 64.1 and 0.555 and you'll get 35.6
C=35.6
And then round it up to the next degree and your finished product is:
36C
