Chapter 1281

Liquid nitrogen is liquid nitrogen.

When the temperature of gas is very low, it will change from gas state to liquid state, and the temperature of liquid nitrogen can be as low as - 196 ℃.

Nitrogen is inert, colorless, odorless, non corrosive and non combustible gas. Nitrogen accounts for 78% of air and is the main component of air.

Thanks to these conditions, liquid nitrogen has become an important raw material for industrial refrigeration.

In order to test the effect of liquid nitrogen on the jelly monster, Li Yun personally lifted a large can of liquid nitrogen and rode the winged monster over it. For the first time, he didn't have to open it and threw it directly.

This thing swallows everything, and liquid nitrogen tanks are no exception.

In the eyes of everyone, the jelly monster happily corrodes the jar, "bang!" With a loud noise, the high-pressure gas inside burst out.

Under higher pressure, the boiling point of liquid nitrogen will be higher. The temperature of liquid nitrogen in this tank is about - 150 ℃.

Jelly monster may be spray silly, silly two seconds to throw away the jar.

And the liquid nitrogen that's spewing out, it's flowing through most of its body, but it doesn't affect it.

"Why?" Jin Liuli just followed Li Yun to watch the excitement and said disappointedly, "it seems to be invalid. This monster has nothing to do with it."

"Don't worry, it will take effect soon."

"Roar!"

As soon as Li Yun finished, the jelly monster screamed. His fat body seemed to be in contact with something terrible. He wriggled away quickly.

And on its body, congealed a group of small white ice, especially on its blue body.

With the spread of liquid nitrogen, the cry of jelly became more desolate, and the wriggling of the body became more violent. It was almost like a man on fire, and he almost rolled on the ground.

The mountain like monster's appearance of escaping is really spectacular.

But finally found the weakness of the monster, people concerned about this incident can not help but be relieved, some people even cheered.

This jelly monster is so stressful.

"This, this liquid nitrogen also has a delay effect?" Jin Liuli looked at Li Yun in surprise, "or did it take a long time to freeze into the monster's body?"

"Neither."

Li Yun said with a smile, "it's because of the Leighton frost effect."

"Leiden What is it? " Golden glaze looks like a curious baby.

"Leighton frost effect" means that when a liquid is poured on a surface whose temperature is higher than its boiling point, it will produce a layer of insulating vapor to prevent the liquid from directly contacting with the surface.

In other words, because the temperature of liquid nitrogen is too low, when it comes into contact with human skin, the huge temperature difference causes the Leighton frost effect to play a role. Liquid nitrogen just skims the surface of the human body, and there is actually a layer of water vapor in the middle to block it. "

Li Yun paused, nodded her smooth forehead and said with a smile, "you really should read more books. No, you didn't invade the foreign computer system before and get a fake university diploma?"

Jin Liuli's face was slightly red. She turned her head and said in a shy voice, "I didn't make it. I asked the people in the sect to help me."

"Oh, there are a lot of talents in Tiandiao Pavilion."

"Hum!"

Li Yun commands the wing demon to fly back, and Jin Liuli can't help saying, "after that, how did the monster get frostbite again? Isn't there an effect at work? "

"It can't be blocked all the time. The temperature can be transmitted. The skin will be frostbitten naturally after the water vapor in the middle is condensed by low temperature."

“…… Oh ~ ~ "
