Boiling Points and Melting Points

Click For Summary
SUMMARY

The discussion centers on the boiling point of olive oil compared to the melting point of tin, as highlighted in Laura Fermi's book, "Atoms in the Family: My Life with Enrico Fermi." It is established that when frying in olive oil, the oil does not reach its boiling point; instead, it is the water in the food that boils, creating the appearance of boiling oil. The boiling point of water is lower than that of olive oil, which explains the cooking process in a tinned skillet.

PREREQUISITES
  • Understanding of boiling and melting points in chemistry
  • Basic knowledge of cooking techniques and frying methods
  • Familiarity with the properties of olive oil and water
  • Knowledge of materials used in cookware, specifically tin-lined copper
NEXT STEPS
  • Research the boiling point of various cooking oils compared to water
  • Explore the thermal properties of tin-lined copper cookware
  • Study the science of frying and the role of moisture in cooking
  • Investigate other culinary misconceptions related to boiling and frying
USEFUL FOR

Chemistry enthusiasts, culinary professionals, and anyone interested in the science of cooking and food preparation.

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?
