Why should a small hole be opened on the lid of the teapot?
On the other hand, when the water boils, pot pressure increases, increases to a certain time (than the outside atmospheric pressure) in the pot steam kettle will burst, loud, lead to dangerous accidents, small teapot on the regulation of inside and outside pressure pot, more security!
This small teapot inside and outside air atmosphere together. When out of water, the water flow out from the kettle mouth, the kettle space increases, the outside air time from Kong Jin to the pot, the pot with the outside pressure of the air pressure, water will continue to flow out of the pot mouth. Without this hole, or the hole plug, the air can't flow into the pot, the water outflow from the spout, the pot of small air pressure, the outside atmospheric pressure, the water in the kettle fell out.
The effect of a teapot opening small holes in a teapot:The small hole on the pot is used to regulate the pressure inside and outside the pot
The small hole on the pot is used to regulate the pressure inside and outside the potWithout a small hole, the pressure in the pot is lower than the pressure outside the potThe air pressure varies from place to place (so that the lid is pressed so thatThe lid of the pot is too tight to openWhen the water boils, the air pressure in the pot increases and increases to a certain point (the pressure is greater than the outside)Steam will open the lid, loud, lead to dangerous accidents.
