Question

1.Почему, когда мы сдавливаем воду в пластмассовой банке с боков,она начинает выливаться горлышка? 2.Почему,когда человек дует в трубку,вода начинаетвыливаться из колбы в стакан?Какое свойство жидкостей и газов здесь проявляется?Умоляю вас!!!!!Помогите!!!!!Заранее спасибо))))))))))

Answer 1

1)Потому, что вода не имеет свойства сжимания!
2) не понял что написала!

Why does water overflow from a plastic bottle when squeezed from the sides?

When you squeeze a plastic bottle filled with water from the sides, the water tends to overflow from the neck of the bottle. This phenomenon can be explained by the properties of liquids, specifically their incompressibility and the Pascal's law.

Liquids are incompressible, which means that they cannot be easily compressed or squeezed into a smaller volume. When you apply pressure to the sides of the bottle, the water inside the bottle cannot be compressed, so it needs to go somewhere. As a result, the water is forced out of the bottle through the path of least resistance, which is the neck of the bottle.

Pascal's law states that when pressure is applied to a fluid in a confined space, the pressure is transmitted equally in all directions. In the case of squeezing a plastic bottle, the pressure you apply to the sides of the bottle is transmitted through the water inside. Since the neck of the bottle is the only opening, the pressure is concentrated there, causing the water to overflow.

To summarize, when you squeeze a plastic bottle filled with water from the sides, the incompressibility of the water and the application of pressure according to Pascal's law cause the water to overflow from the neck of the bottle.

Why does water overflow from a flask into a glass when blown into a tube?

When a person blows into a tube connected to a flask filled with water, the water starts to overflow from the flask into the glass. This phenomenon can be explained by the properties of liquids and gases, specifically their ability to flow and the principle of displacement.

Liquids and gases can flow, meaning they can move and change shape when subjected to external forces. When you blow into the tube, you create a flow of air that enters the flask. This flow of air displaces the water inside the flask, causing it to move and overflow into the glass.

The principle of displacement states that when an object is placed in a fluid, it displaces an amount of fluid equal to its own volume. In this case, when you blow into the tube, the air you blow displaces an equal volume of water inside the flask. As a result, the water is pushed out of the flask and into the glass.

To summarize, when a person blows into a tube connected to a flask filled with water, the flow of air displaces the water inside the flask according to the principle of displacement, causing it to overflow into the glass.

I hope this explanation helps! Let me know if you have any further questions.
