How did Daniel Fahrenheit come up with the points of 32 degrees for freezing and 212 degrees for boiling?

Answer 1

Instead of typing out the entire story (or supposed stories), I will supply you with the link that goes over how Fahrenheit established his temperature scale.

Answer 2

As I recall he used the lowest temperature achieveable in his lab at the time as zero, by using a mixture of ice, ammonium chloride and water. Some say he used his body temperature as 100, though that might suggest he had a fever at the time? Anyway, freezing at 32 and boiling at 212 fall where they do based on these two "constants".

Answer 3

enable's not grant Anders Celsius too plenty credit. In 1742 he proposed a scale on which 0 levels grew to become into the boiling element of water and one hundred levels grew to become into freezing element. It wasn't until finally 2 years after Celsius' death that Carl Linnaeus inverted the dimensions putting 0 levels as freezing element. by utilising hundred divisions the dimensions grew to become into talked approximately simply by fact the Centigrade scale, the gadgets being talked approximately as levels C. Centigrade, in spite of the easy certainty that, grew to become appropriate right into a term already in use - for a million/10000 of a desirable strategies-set, so a sparkling call grew to become into required for the temperature scale. Centigrade grew to become into abandoned in favour of levels Celsius. So previous Anders, who fouled the dimensions up contained interior the 1st place, have been given the credit . Fahrenheit set his 0 levels on the freezing element of ice, brine and ammonium chloride. He did not use the freezing element of water as a fastened element.. His diverse fastened element ninety six levels grew to become into the temperature of the human physique (corrected by later workers to ninety 8.6 levels. John H
