Two thermometers are calibrated by measuring the freezing point of glacial acetic acid, which is 16.6 °C. Equal numbers of measurements are taken with each thermometer. The result from the first thermometer is 16.4 ± 0.2°C and the result from the second thermometer is 16.8 ± 0.1°C.

a. Is it possible to tell which thermometer is more accurate? If so, say which one. If not, explain why.

b. Is it possible to tell which thermometer is more precise? If so, say which one. If not, explain why.

Step 1 of 3:

It is given that two thermometers are calibrated by measuring the freezing point of glacial acetic acid which is found to be 16.C.

The result from first thermometer with equal number number of measurements as second thermometer is 16.4C.

Result from the second thermometer is 16.8C.

Using these data we have to answer the given questions.

Step 2 of 3:

(a)

Here we have to identify which thermometer is more accurate.

It is given that result from first thermometer is 16.4C or it lies between (16.,16.C) and result from thermometer is 16.8C or it lies between (16.,16.).

Here we can observe that true value 16.C is observed from the first thermometer.

So we can conclude that first thermometer is more accurate.
