Three (1) years ago Daniel Gabriel Fahrenheit made his (2) thermometer in
his home town of Danzig (Now Gdansk in Poland). The thermometer was filled with (3)
and completely sealed, but it was not much use without some sort of (4) to measure the
temperature.
One story (5) that, during the winter of 1708—1709,Fahrenheit took a measurement
of 0 degrees as the coldest temperature outdoors—which would now read as minus 17.8°C. Five
years (6) he used mercury instead of alcohol for his (7) ,and made a top reference
point by measuring his own body temperature as 90 degrees. Soon afterwards he became a glassblower, (8)______allowed him to make thinly blown glass tubes that could be marked up with more points on the scale and so (9)______accuracy.
Eventually he took the (10) point of his temperature scale from a reading made in ice,
water and salt, and a top point made from the boiling point of water. The scale was recalibrated
using 180 degrees between these (11) points and Fahrenheit was able to make much more
accurate and more (12) measurements of temperature.
But in 1742 a rival challenged the Fahrenheit scale and (13) superseded it. Anders
Celsius, in Sweden, invented a scale of 100 degrees between the freezing and boiling points of
water and gradually (14) over many countries. However, the British (15) wedded to
Fahrenheit until well into the 20th century.
