Question

Среди описанных случаев выбери примеры диффузии. 1) хорошо надутый и сдавленный руками мяч быстро восстанавливает свою прежнюю форму, если убрать руки.2) Маленький резиновый воздушный шар, наполненный гелием, через некоторое время сдувается. 3) в багажнике машины лежат книга и мяч. Когда машина тронулась, мяч покатился. 4) Открытый сосуд с углекислым газом помещают на рычажные весы и уравновешивают гирьками. Наблюдая некоторое время за уравновешенными весами, замечают, что равновесие весов нарушилось. 5) в любую погоду дым из трубы дома постепенно перестаёт быть видимым через небольшой промежуток времени,​

Examples of Diffusion

1) A well-inflated and squeezed ball quickly regains its original shape when the hands are removed. This is an example of diffusion because the air molecules inside the ball move from an area of high pressure (when the ball is squeezed) to an area of low pressure (when the hands are removed), causing the ball to regain its shape [[1]].

2) A small rubber balloon filled with helium gradually deflates over time. This is another example of diffusion. Helium molecules, being lighter than air molecules, gradually escape through the rubber balloon's material and mix with the surrounding air, causing the balloon to deflate [[2]].

3) In the trunk of a car, there are a book and a ball. When the car starts moving, the ball rolls. This is an example of diffusion due to the force of gravity. The ball moves from a higher position (on top of the book) to a lower position (rolling on the floor of the trunk) as the car accelerates [[3]].

4) An open vessel containing carbon dioxide gas is placed on a lever balance and balanced with weights. After some time, the balance is disturbed. This is an example of diffusion. The carbon dioxide molecules inside the vessel gradually escape into the surrounding air, causing a change in the mass on the lever balance and disturbing the equilibrium [[4]].

5) Smoke from a house chimney gradually becomes less visible over time, regardless of the weather conditions. This is an example of diffusion. The smoke particles disperse and mix with the surrounding air, making them less concentrated and less visible to the naked eye [[5]].

These examples illustrate different instances of diffusion, where particles or molecules move from areas of high concentration to areas of low concentration, resulting in the equalization of their distribution.
