Question

Как объяснить, что атмосферное давление уменьшается по мере увеличения высоты подъема над уровнем моря

Answer 1

Это объясняется тем, что с увеличением высоты толщина сжимающего слоя атмосферы уменьшается.
Однако в отличие от давления в жидкостях изменение атмосферного давления не пропорционально Л, а происходит гораздо быстрее, что объясняется уменьшением плотности атмосферы с увеличением высоты.

Answer 2

Explanation of Atmospheric Pressure Change with Altitude

Atmospheric pressure refers to the force exerted by the weight of the air above a given point. As altitude increases, the atmospheric pressure decreases. This phenomenon can be explained by the following factors:

1. Decrease in Air Density: As altitude increases, the density of the air decreases. This is because the air molecules are spread out over a larger volume at higher altitudes, leading to a decrease in the number of air molecules per unit volume. This decrease in air density results in a decrease in atmospheric pressure.

2. Effect of Gravity: Gravity pulls the air molecules towards the Earth's surface. As altitude increases, the gravitational force acting on the air molecules decreases, leading to a decrease in the weight of the air column above a given point. This reduction in weight contributes to the decrease in atmospheric pressure with increasing altitude.

3. Vertical Distribution of Gases: Different gases in the atmosphere have varying weights. As altitude increases, the lighter gases tend to rise to higher altitudes, leading to a decrease in the overall pressure exerted by the atmosphere at that altitude.

In summary, the decrease in atmospheric pressure with increasing altitude is primarily due to the decrease in air density, the diminishing effect of gravity, and the vertical distribution of gases in the atmosphere.
