Gabriel Daniel Fahrenheit GD Fahrenheit was the German physicist who invented the Fahrenheit scale. He was not successful at being a shopkeeper. He was a glass blower, and an instrument maker. He was born on May 24 th, 1686 in Gdansk, Poland. This was a time when heat could not be measured. He invented the alcohol thermometer in 1709.
Then, he invented what we use in America today, the mercury thermometer, in 1714. But what he is most famous for is inventing the Fahrenheit scale. Scientists stopped using the scale and started using the more sensible Celsius scale, invented by Anders Celsius. Fahrenheit spent a lot of his life studying physics. He discovered many things, including that water does not have to boil at its boiling point. This is due to the variation of atmospheric pressure.
He decided the freezing point should be 30 degrees, and the average body temperature should be 90. These were later revised to 32 degrees and 98. 6 degrees. The expression to convert Fahrenheit to Celsius is F = (9/5 C) +32. In Layman’s terms, just subtract 32, divide by 9 and then multiply by 5. Country’s now use the Celsius scale because of the more sensible freezing point 0 and boiling point 100.
America is only country left to use Fahrenheit. Maybe this is because Gabriel worked a little harder when inventing his scale. He did many experiments with ice water and salt water before he came up with any numbers. He also worked for months before coming up with the mercury thermometer.
The Essay on Effects Of Salt On Freezing Point Of Water
Blank 1 Blank ity BlankBlankity Blank Mr. Blank 4/9/02 Effects of Salts on the Freezing Point of Water In this experiment, you will study the effect that several solutes have on the Freezing Point of water. When a solute is dissolved in a liquid, the temperature at which that liquid freezes decreases, because the molecules of the solute become attached to the water molecules, making it more ...
This is an invention respected because mercury will not stick to the glass tube, unlike alcohol. We take the thermometer for granted. Without it, weather would be hard to predict. GD Fahrenheit deserves credit because without his ingenious inventions and experiments, the Meteorologists would be out of the job.
