為什麼在沸水煮雞蛋 雞蛋熟了會浮在水面上呢?

最佳解答:
If you compare the weights of a raw egg and a boiled egg, you can find that the weight of a boiled egg is smaller than a raw egg. The difference of the weights is due to the loss of water content within the egg shell during boiling. During boiling, the water molecules within the egg shell become evaporated and escape through the egg shell into the surrounding boiling water. As the water content within the egg shell decreases gradually, the boiled egg becomes lighter and it finally floats on the boiled water.
