high altitude chambers
The fuselage of most aircraft is not strong enough to withstand that pressure. The air pressure is very low at high altitudes, and if the inside pressure was set to 0 ft (an extremely high pressure), the fuselage would burst.
To allow passengers to breathe sufficient oxygen, needed to survive, even in high altitudes.
It is greater at a lower altitude.
No, it is not. The pressure decreases as the altitude increases.
No, they will drop to normal a few weeks after returning to normal altitudes.
The pressure cooker altitude chart provides information on how to adjust cooking times and pressure levels when cooking at high altitudes. This is important because the lower air pressure at higher altitudes can affect the cooking process in a pressure cooker.
At higher altitudes, the air pressure decreases because the air molecules are more spread out. This reduction in pressure means there are fewer oxygen molecules available in the air to be breathed in, leading to lower oxygen levels at high altitudes.
At high altitudes, the air is thinner and there is less pressure. This causes the air to expand and cool down, leading to lower temperatures.
as their is high pressure inside and low pressure outside and air moves
The higher the vapor pressure of a liquid at a given temperature, the lower the normal boiling point (i.e., the boiling point at atmospheric pressure) of the liquid.
medium pressure
At high altitudes, cooking times in a pressure cooker may need to be increased due to lower atmospheric pressure. This is because water boils at a lower temperature at higher altitudes, which can affect the cooking process. Additionally, the pressure levels in a pressure cooker may need to be adjusted to compensate for the lower atmospheric pressure at high altitudes in order to ensure proper cooking.
