Which statement explains which thermometer is MORE appropriate to measure the temperature of a liquid at 43.6 degrees Celsius A) Thermometer A, because it measures temperature more accurately than thermometer B

B) Thermometer B, because it measures temperature more accurately than thermometer A

C) Thermometer A, because it measures temperature more precisely than thermometer B

D) Thermometer B, because it measures temperature more precisely than thermometer A

Option A.

Explanation:

According to the attached picture (which I'm assuming is the same that you have, but you forgot to attach) let's see wchi thermometer will help to measure the temperature of this liquid at 43.6 °C

In thermometer A, we can see that the the measures of temperatures are measured to the tenth digit. This means that the measures would be more accurate, and this is precisaly what we want in this case, because the temperature we need to measure is 43.6 °C.

Thermometer B measures to 1 digit only, therefore, is less accurate than thermometer A, and the measure would not be readable with accuracy.

Remember that accuracy is related to the closeness of a standard value, while the precision is related to the closeness of two or more measures.

In this problem we do not have several measures, just one, and we need to do it with more accuracy, so thermometer A would fullfill this.

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).
