Question

Как изменится давление на батискаф, погруженный в море, если глубина погружения не изменится, а атмосферное давление уменьшится? 1) увеличится 2) уменьшится 3) останется прежним 4)нельзя дать однозначный ответ

Answer 1

Давление на батискаф уменьшится

P = Po  +   Pж
если давление атмосферы  Po уменьшается то и давление на батискаф тоже уменьшится

Answer 2

Effect of Atmospheric Pressure Change on a Submerged Bathyscaphe

When a bathyscaphe is submerged in the sea and the atmospheric pressure decreases while the depth of submersion remains constant, the pressure inside the bathyscaphe will decrease.

The reason for this is that the pressure inside the bathyscaphe is determined by the difference between the external water pressure and the internal air pressure. If the atmospheric pressure decreases, the external water pressure remains the same, causing a decrease in the overall pressure inside the bathyscaphe.

This can be explained by Boyle's Law, which states that the pressure of a given mass of gas is inversely proportional to its volume at constant temperature. As the atmospheric pressure decreases, the volume of the air inside the bathyscaphe will increase, leading to a decrease in pressure.

Therefore, the correct answer to the question is 2) уменьшится.
