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.
It is greater at a lower altitude.
To allow passengers to breathe sufficient oxygen, needed to survive, even in high altitudes.
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.
as their is high pressure inside and low pressure outside and air moves
medium pressure
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.
because there is low pressure at higher altitudes
exist at the earth's surface and at high altitudes
Because plasma cells contain inert gases and the pressure increases at higher altitudes causing increased heat in plasma televisions. LCD televisions do not have any problems at high altitudes.
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.
