The 'strange' thing happens when gasoline and liquid nitrogen meet

Liquid nitrogen is a very unique chemical from which many interesting experiments can be made that you will see soon.

Chemical experiment between gasoline and liquid nitrogen

For chemical enthusiasts, liquid nitrogen is considered one of the most interesting chemicals, with many unique experiments, such as dropping table tennis into liquid nitrogen.

But today we are going to come up with some more interesting experiments: See liquid nitrogen can react with gasoline - a fuel that is very close to us.

Put liquid nitrogen into gasoline

Immediately, we could see white smoke covering the entire gas cup.

However, look at how the nitrogen droplets move. Why is it so strange?

The reason for this is due to an effect called " Leidenfrost effect " - Leidenfrost effect - discovered by scientist Johann Gottlob Leidenfrost in 1796.

Accordingly, when a liquid comes into contact with another liquid surface with a boiling point much higher, it will form a cleavage of gas between the two liquids. And the special point is that even though the contact temperature is much higher than the boiling temperature, the liquid will turn slightly slower than when it approaches the boiling temperature of the substance.

In this case, liquid nitrogen with a boiling temperature of -196 degrees Celsius, the Leidenfrost effect will occur when exposed to gasoline, causing the nitrogen droplet to appear " floating " on the gasoline surface. When liquid nitrogen hits the cup mouth, it will "boil" again, forming a push in another direction. Just like that until the nitrogen drops completely dissipate.

Fuel gasoline into liquid nitrogen

So in the other case, we put gasoline in liquid nitrogen, what will happen?

Unexpectedly, gasoline will cause a small amount of liquid nitrogen to evaporate, forming smoke in the cup mouth.

However, due to lower gasoline, the temperature produced is not enough to evaporate all liquid nitrogen. On the contrary, we have a "gas" because at this time gasoline has been frozen.

The reason is because when two objects have a difference in contact temperature, the temperature will move from a larger temperature to a cooler one, until the heat becomes balanced. In this case, because the amount of gasoline is too small, the equilibrium temperature is very low, enough to cause the "gas department" to freeze.

* Note: Liquid nitrogen will cause cold burns if in direct contact, so be sure of safety conditions before performing this test.
