In order to inhale a breath of air, you enlarge the chamber that holds your lungs (by drawing
your diaphragm down). As the container becomes larger, the atmosphere comes pouring into
the lungs, and the amount that pours in depends on the atmospheric pressure. If the pressure
of the atmosphere around you were 50% less, then the same volume of air would flow in, but
it would have only half as many oxygen molecules in it, and your body would have trouble
keeping your fires going. That's why you can feel faint and light-headed just being up on a
mountain for a while. A commercial airliner travels at an altitude that's about a mile higher
than the top of Mt. Everest. The atmospheric pressure at that altitude is so low that you couldn't
stay conscious for very long with the amount of air you'd get by just opening up your chest cavity
and waiting for it to pour in.

What kind of inclined plane are there?
There are many kinds of inclined planes. Some examples are: driveways, slide, and a ramp. There are many kinds of inclined planes. Some examples are: driveways, slide, and a ramp.
What are the properties of a convex plane and how does it differ from other types of planes?
A convex plane is a flat surface that curves outward, like the outside of a sphere. It has no indentations or concave areas. This differs from other types of planes, such as concave planes, which curve inward, and flat planes, which have no curvature at all.
What is the significance of the family of planes in crystallography and how are they represented using Miller indices?
In crystallography, the family of planes refers to a group of crystal planes that share similar characteristics. These planes play a crucial role in determining the structure and properties of crystals. Miller indices are used to represent these planes in crystallography, providing a standardized way to describe their orientation and spacing within the crystal lattice. By understanding the family of planes and their Miller indices, scientists can analyze and predict the behavior of crystals in various applications.
What are examples of special inclined planes?
Examples of special inclined planes include ski slopes, wheelchair ramps, and water slides. These inclined planes are designed for specific activities or purposes that involve movement along a sloped surface.
What are the different types of planes that belong to the same family of aircraft?
The different types of planes that belong to the same family of aircraft are typically categorized based on their size, purpose, and design. Some common types include commercial airliners, regional jets, turboprops, and cargo planes. These planes share similarities in their overall structure and technology, but are tailored for specific roles within the aviation industry.
What is the advantage of using a pressurised nuclear reactor?
In a pressurised nuclear reactor the temperature is very high, which cn be accepted as a point for this.
Why do an aeroplane are often 'pressurised'?
As aeroplanes fly high in the atmosphere, where the air is thin, the inside has to be pressurised to allow the passengers and crew to breath.
How can submarines float and sink?
Submarines change their depth by use of ballast tanks. To dive, they open their tanks so that they become filled with water. They also angle their dive planes. To surface, they pump the water out of their tanks and fill them with pressurised air.
Can you take pressurised cans onto flights?
no
How do people get in space?
They take it with them, in pressurised tanks.
Why can you wear ordinary clothes in a space shuttle?
because it has been pressurised in a similar way (outcome) to how a commercial airplane is pressurised for passengers to fly at altitude.
Experience of working in a pressurised and busy environment?
yes
Does the temperature of nitrogen increase when it is pressurised?
Generally, yes
What is the necessity of pressurised cabins in aeroplanes?
no your gonna die
What brewery was first to introduce keg beer?
Keg beer is a term for beer which is served from a pressurised keg. Watney's (UK) started with an experimental pressurised beer Red Barrel which was served in a pressurised Keg rather than the traditional Cask (barrel) in 1936. The use expanded rapidly circa 1960
Difference between hydraulics and pneumatics?
hydraulic is liquid based, pneumatic is air.
Why is liquid cooling system pressurised?
to increase the boiling point of the coolant
