A student collected the data shown in the table below during an experiment. Liquid Characteristics
Liquid Characteristics
Boiling Point Freezing Point Color Toxicity
Mercury 357 °C −39 °C shiny silver gray hazardous if tube is broken
Alcohol 78 °C −115 °C colorless relatively non-hazardous

Based on the data, which of the following conclusions can be made about the use of mercury and alcohol thermometers?
An alcohol thermometer can easily measure the boiling point of a colorless liquid that boils at 100 °C.
A mercury thermometer can easily measure the boiling point of a colorless liquid that boils at 82 °C.
A mercury thermometer can easily measure the freezing point of a colorless liquid that freezes at −50 °C.
An alcohol thermometer can easily measure the freezing point of a colorless liquid that freezes at −110 °C.

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).
