煮熟的饺子为什么会浮起来?

来源: 日期:2020-07-20

  随着火炉的加热,锅中的水和饺子慢慢的热了起来。我们知道热的物体要膨胀的,饺子也不例外。饺子馅和饺子皮吸饱了热之后,渐渐膨胀起来,体积自然就增大了很多,但是饺子的质量并没有增加,当体积增大后,单位体积的质量就减小了。等到饺子煮熟,饺子馅和饺子皮都充分膨胀以后,他的密度就比水的密度还小,所以就浮在水面上了。
  With the heating of the stove, the water and dumplings in the pot slowly heat up. We know that hot objects expand, and dumplings are no exception. After the dumpling stuffing and dumpling skin absorb the heat, gradually expand, the volume naturally increases a lot, but the quality of dumplings does not increase, when the volume increases, the mass per unit volume decreases. When the dumplings are cooked, the dumpling filling and the dumpling skin are fully expanded, the density of the dumpling is smaller than that of the water, so it floats on the water.

  (一个物体在水中所受的浮力和它的排水量有什么关系?物体浮或沉除了浮力,还和哪一因素有关?)饺子或肉丸在制作过程中,内部含有微量空气和二氧化碳。当刚投入水中时,由于饺子或肉丸的密度比水大,浮力小于重量,就沉入锅底。
  (what is the relationship between the buoyancy of an object in water and its displacement? Besides buoyancy, which factor is related to the buoyancy of an object Dumplings or meatballs contain trace amounts of air and carbon dioxide in the making process. When they are just put into the water, because the density of dumplings or meatballs is higher than that of water and the buoyancy is less than the weight, they sink into the bottom of the pot.
  当加热至煮熟后,内部的气体和肉质都同时膨胀,整个饺子或肉九的体积就增大许多,也就增大了它的排水量。根据阿基米德原理(Archimedes'principle)可知,饺子或肉丸的浮力就增大了,这时浮力大于重量,就浮起来了。
  When heated to cooked, the internal gas and meat quality expand at the same time, the volume of the whole dumpling or meat nine will increase a lot, which will increase its drainage. According to Archimedes' principle, the buoyancy of dumplings or meatballs increases, and when the buoyancy is greater than the weight, it will float.
