Suck the air out of a container and watch it being crushed.
Look at a balloon. Its round shape tells you that the pressure (atmospheric) from outside acts equally from all directions. Now take that balloon up a mountain and watch the balloon get bigger. There is less atmospheric pressure acting on the outside of the balloon the higher you go so the pressure inside the balloon makes the balloon bigger.

What is the relation between pressure in atmosphere and pressure?
Atmospheric pressure is the surrounding pressure around us. We live in the atmosphere and treat the atmospheric pressure as the base pressure. A pressure gauge would read 0 at atmospheric pressure. When we define the pressure in scientific way of absolute pressure, we need to add up an atmospheric pressure to the measured pressure.
Does absolute pressure in a liquid of constant density double when the depth is doubled?
No, the absolute pressure in a liquid of constant density would not double in this situation. This is because the atmospheric pressure is an independent variable, so it will keep the absolute pressure from doubling.
How do you detect leak in a vacuum chamber?
The simplest method would be to mount a pressure gauge onto the chamber, then to observe whether the reading changes. It should remain at "zero" indicated gauge pressure. If your instrumentation is relative to atmospheric pressure, it would be a "minus" pressure and would vary with local atmospheric pressure. For very accurate readings, you would need something more sophisticated, such as an ionisation gauge.
Why are you not crushed by atmosperic pressure?
Because your structure has evolved in order to withstand atmospheric pressure. A creature that could not survive atmospheric pressures would not be able to survive, and therefore would not be able to produce offspring. All of the body's tissues contain dissolved air (nitrogen & oxygen) at pressure equilibrium with the atmosphere. In effect the body "pushes back" against atmospheric pressure, just as ocean creatures withstand crushing water pressure by mostly consisting of water.
Why is the atmospheric pressure is lower at the top of a mountain than in a valley?
Atmospheric pressure is the force per unit area exerted against a surface by the weight of air above that surface in the Earth's atmosphere. In most circumstances atmospheric pressure is closely approximated by the hydrostatic pressure caused by the weight of air above the measurement point. Low pressure areas have less atmospheric mass above their location, whereas high pressure areas have more atmospheric mass above their location. Similarly, as elevation increases there is less overlying atmospheric mass, so that pressure decreases with increasing elevation. A column of air one square inch in cross-section, measured from sea level to the top of the atmosphere, would weigh just over a stone (and a column one square centimetre in cross-section would weigh just over a kilogram).

Would a human get smashed if the got on Venus?
A human would be crushed by the intense atmospheric pressure, which is 90 times that of the Earth's atmospheric pressure.
Is barometric pressure the same as atmosheric pressure?
Yes, Barometric Pressure and Atmospheric Pressure are the same thing. Except one describes what Atmospheric Pressure would be measured in.
Who uses atmospheric pressure?
If you mean, who needs to know what the atmospheric pressure is, that would be meteorologists. If you mean, who makes use of the atmosphere, that would be everybody who breathes.
To measure a pressure above atmospheric pressure you would use?
You would use a mercury manometer
To measure pressure above atmospheric pressure you would use a?
mercury manometer
What would happen to the air pressure if you took a barometer from a mountain top down into a mine shaft?
the atmospheric pressure on top of a moutain would be lower than the atmospheric pressure down in a mine shaft
State and explain how the boiling point of water will change if the atmospheric pressure falls?
Water boils when its internal pressure reaches that of the atmospheric pressure. Therefor, if one lowers the atmospheric pressure, the water would boil at a lower temperature (in fact, one can make water boil at room temperature by dramatically lowering the atmospheric pressure).
Would you consider atmospheric pressure when finding the pressure of a liquid in a closed container?
pressure is usually measured relative to atmospheric this is called gauge pressure. if you compare against absolute zero pressure (vacuum) this is called absolute pressure.
Where on earth would you expect atmospheric pressure to be highest?
at the surface
How would you describe an anticyclone?
A region of high atmospheric pressure.
Why is atmospheric pressure greater at sea?
Atmospheric pressure is the weight of the air above the point... at sea level there is more air above the point then there would be at 10,000ft
