Supercooling is the procedure of cooling a liquid below its normal freezing point without freezing (Science Daily). How does it do that? Why does it do that? Who came up with it? Get ready, because supercooling is super cool.
Supercooling is a state where liquids doesn't freeze below their normal freezing point 32 degrees (ESRF). The liquid is stuck in something called a metastable state. This is state where something can exist in long lived states that are less stable than the liquids most stable form. This can only be achieved if there is no seed to trigger the crystallization process. A good example of this is clouds at a high altitude. The clouds contain tiny ...view middle of the document...
Crystalline impurities is what causes the liquid to change into a solid. A crystalline impurity can be something like a speck of dust or a piece of ice. The ice crystal is a starter for more ice crystals (business insider).
The man who discovered supercooling was Daniel Gabriel Fahrenheit. He was born in 1686 in Gdansk, Russia. He went to school for business, but he also trained in natural sciences, which he liked very much (InDepthInfo). Later he worked in the fields of Chemistry and Engineering. In the 1710 he traveled to Amsterdam where he gave
lessons in Chemistry. Then in 1724 he became a member of the Royal Society in Great Britain. After settling down in Amsterdam he did a lot of scientific work and made many discoveries, including the method of supercooling water. Fahrenheit needed a way to find an objects temperature based on the objectives source (InDepthInfo). So he took the lowest temperature to which he could supercool a liquid without it freezing and set that as the beginning point for his scale. This temperature was 32 degrees. The temperature of the human body was set at 98.6 degrees. Not long after he made this discovery, he died in 1736.
Here are a few methods that can be used to achieve supercooling. One method is to take a bottle of room temperature pop and start shaking it violently. Then place it in the...
