Appearance My name is a thermos, and people often call me a thermos. I was able to put hot water and keep it hot for a long time, and it was still hot when people were drinking.

How do I have this feature? This is mainly due to my stomach gall. The gall is made of double glass, with a vacuum in the middle, which makes it difficult to transfer heat, and the glass is also plated with a layer of mercury, so that the heat is constantly reflected back, so that the water temperature can be maintained.

Gall cork Despite the gall, the heat can be transferred through the upper opening, so add a cork to the opening to block the last pass of heat transfer, so that it is foolproof.

Finally, add a lid on top of it, which is both beautiful and hygienic. You're welcome to use it!

My name is Hot Water Bottle. My biggest feature and main function is insulation. I'm a beautiful thermos because I have a pale pink dress and a cute Mickey Mouse on it.

I also have a square "head" that is even more colorful. There is very hot water in my "belly", as long as the little master picks up my reed, it must be hot, this is the transmission of heat energy. There are three forms of propagation of heat energy:

One is conduction, the second is convection, and the third is radiation. To keep warm, it is necessary to take corresponding measures for these three situations to prevent heat loss. In order to prevent heat conduction, people use glass to make the heart part - the bottle gallbladder.

Glass has the disadvantage of being fragile, but it is a bad conductor of heat, and it is perfect to use it for my heart. In order to prevent convection, the bottle is made into a double layer, and the air in the interlayer is pumped out to make it a sealed vacuum. In this way, the cold air outside can't touch my heart, which effectively blocks my heat channel.

My vacuum protective layer, like a "heavenly coat" without a single gap, is perfect for maintaining the temperature of my heart. In order to prevent the occurrence of thermal radiation, a layer of mercury is plated on the wall of the bottle to make it a mirror state. This reflects not only light but also heat.

Once the radiant heat touches this smooth mirror, it's like a leather ball hitting a copper wall, ** go back, how about it, is it fun? In short, I made it scientifically according to the principle of heat. Therefore, our thermos have an eternally fiery heart to serve humanity.
