Question

Почему воздушный шарик,наполненный водородом , при подьеме над Землёй увеличивается обьеме? Докозать

Answer 1

С высотой наружное давление уменьшается, а давление водорода внутри остается прежнем( если не учитывать перепад температур)

Answer 2

Why does a hydrogen-filled balloon increase in volume as it rises above the Earth?

When a hydrogen-filled balloon rises above the Earth, it increases in volume due to several factors. Let's explore these factors in more detail:

1. Decrease in atmospheric pressure: As the balloon ascends, it moves into regions of lower atmospheric pressure. The pressure exerted by the surrounding air decreases with increasing altitude. This decrease in pressure allows the gas inside the balloon to expand, causing the balloon to increase in volume.

2. Boyle's Law: Boyle's Law states that the volume of a gas is inversely proportional to its pressure, assuming the temperature remains constant. As the pressure on the hydrogen gas inside the balloon decreases with altitude, the gas expands to occupy a larger volume to maintain equilibrium.

3. Ideal Gas Law: The Ideal Gas Law combines Boyle's Law with other gas properties, such as temperature and the number of gas molecules. According to the Ideal Gas Law, when the pressure decreases and the temperature remains constant, the volume of the gas increases. This principle applies to the hydrogen gas inside the balloon as it rises above the Earth's surface.

4. Gas behavior: Hydrogen gas is highly compressible and can easily expand or contract in response to changes in pressure. As the balloon rises and the external pressure decreases, the hydrogen gas inside the balloon expands to fill the available space, causing the balloon to increase in volume.

In summary, the increase in volume of a hydrogen-filled balloon as it rises above the Earth is primarily due to the decrease in atmospheric pressure, Boyle's Law, the Ideal Gas Law, and the compressible nature of hydrogen gas.
