Put vinegar in the oil and boil it, why it won t burn your hands

Vinegar has a low boiling point and is denser than oil....When the vinegar is boiling, the oil floats on it, so it looks as if the oil is boiling, giving the illusion that the temperature is high, but the actual temperature is not high, so it is not hot! If you don't understand it yet, you can continue to ask me.

This question involves several aspects of chemistry and physics. First of all, we need to understand the respective properties of vinegar and oil.

Vinegar is an acidic liquid whose chemical composition is acetic acid (CH3COOH). When heated, vinegar has a lower boiling point than water, only about 60 degrees. This means that when the vinegar is heated to this temperature, it will start boiling, creating bubbles.

Oil, on the other hand, is an organic compound that typically has a higher boiling point than water. Specifically, the boiling point of different kinds of oil may vary, but it is usually above 200 degrees. This means that when the oil is heated to this temperature, it will only start boiling.

In the case of "vinegar in oil", the vinegar will start to boil when heated to about 60 degrees due to the low boiling point of the vinegar. However, due to the higher boiling point of the oil, at this temperature, the oil does not boil. So, even though the liquid in the pot looks like it's boiling, only the vinegar below is actually boiling, and the oil floating on top isn't boiling.

Also, since vinegar is denser than oil, when blending, the vinegar sinks underneath and the oil floats on top. This means that most of what your hands come into contact with is vinegar, not oil. And the human hand can usually withstand a temperature of forty or fifty degrees, so in this case, the hand will not burn.

Overall, from an ingredient list perspective, this is because vinegar and oil have different boiling points; From the point of view of the production process, this is because the vinegar boils first when heated, and due to the high density of vinegar, most of the vinegar that comes into contact with the hand is vinegar, not oil.

Because the density of oil is greater than that of vinegar, this is the principle of chemistry. When heated, the oil sinks and the vinegar floats up, and when you see it boiling, it's not oil, it's vinegar. That's how most people do magic.

There is vinegar under the oil pot, the boiling point of the oil is high, the boiling point of the vinegar is low, after the vinegar boils, it will smoke and rise to the surface, because the boiling point of the upper oil is low, so at this time, the oil has not yet boiled, but the warm and warm Sun Zheng, not feeling hot, of course, there is no regret at all!

The boiling point of edible oil is generally above 200. When the oil temperature exceeds 250, harmful substances such as butadienorein will be produced, which seriously endanger human health and can cause cancer. The boiling point range (also known as the boiling range) of gasoline is 30 205°C, and the boiling point range of diesel is 180 370 and 350 410.

The boiling point of water is determined by the air pressure, the air pressure is high, the boiling point is high, the air pressure is low, and the boiling point is low, which is generally considered to be 100. The boiling point of vinegar is lower, generally at 37 42, so it doesn't matter if you close the boiling vinegar.
