Boiling Points and Melting Points

Click For Summary
In "Atoms in the Family: My Life with Enrico Fermi," Laura Fermi discusses the science behind frying food in olive oil, highlighting a key point: while olive oil has a higher boiling point than tin, it does not boil during frying. Instead, it is the water content in the food that reaches its boiling point, creating steam and giving the appearance of boiling oil. This distinction clarifies that the oil itself remains below its boiling point during the cooking process. Additionally, the conversation touches on the boiling points of water and olive oil, emphasizing that water boils at a lower temperature, which is crucial for understanding frying dynamics. The discussion invites further exploration of similar scientific questions related to cooking and temperature.

In Atoms in the Family: My Life with Enrico Fermi, Laura Fermi explains some of the games they played when they were in college. The following is an excerpt from the book which I need help understanding.

"As you know, the boiling point of olive oil is higher than the melting point of tin. How can you explain that it is possible to fry in olive oil inside a tinned skillet?" (The best Italian skillets are made of tin-lined copper.)
Despite her trepidation Ginestra was able to figure out the correct answer:
"Oil does not boil, when frying. It's the water in the food that boils!"

So, does this mean that the olive oil doesn't actually reach the boiling point, but that the water is what is boiling, Right? And that the water makes the oil seem like it is boiling when it isn't actually boiling?

Do you know of any more type of tricky questions?

Yes.
 
Would it help to know that the boiling point of water is lower than the boiling point of olive oil?
