Question

почему когда чайник кипятиться, из носика выливается вода? (Физика) когда чайник полный

Answer 1

Пузырьки видели при кипении воды? Вот эти пузырики имеют объем, и вытесняют воду на количество равное обьему пузырьков.

Answer 2

При нагревании вещество (в частности, вода) расширяется и занимает больший объём.

Answer 3

Why does water pour out of the spout when a kettle is boiling? (Physics)

When a kettle is boiling, water pours out of the spout due to the phenomenon known as the "teapot effect" or "kettle effect." This effect occurs because of the interaction between the boiling water and the steam produced.

When water is heated in a kettle, it reaches its boiling point and starts to evaporate, forming steam. As the steam rises, it creates a pressure difference inside the kettle. The pressure inside the kettle becomes higher than the atmospheric pressure outside.

To equalize the pressure, the steam tries to escape through the spout. However, the spout is narrow, creating a bottleneck. As a result, the steam pushes the water in the kettle, causing it to rise and flow out of the spout along with the steam.

This phenomenon is similar to how a teapot pours when it is tilted. The steam escaping from the spout creates a partial vacuum inside the kettle, which pulls the water up and out of the spout.

In summary, when a kettle is boiling, water pours out of the spout due to the pressure difference created by the escaping steam.
