Why do one not crushed under the weight of air above us?
The air pressure inside our bodies matches the air pressure outside, so there is equilibrium. Our bodies are also designed to withstand the pressure exerted by the weight of the air above us through structural integrity and the balance of internal and external pressures.
Is air pressure greater when your higher up or lower?
Air pressure is greater at lower altitudes because the weight of the air above compresses the air below, leading to higher pressure. As you go higher in altitude, the air pressure decreases due to the lower weight of air above.
What is the pressure above sea level in mmHg?
The atmospheric pressure at sea level is typically around 760 mmHg. As you increase in altitude above sea level, the atmospheric pressure decreases. For example, at 5,000 feet above sea level, the atmospheric pressure may be around 625 mmHg.
How is pressure affected by the depth below the surface of a fluid?
Think like this if you but sand in a bucket with a balloon in the bottom will the balloon be crushed? its the same way with water or any liquid the deeper you go the more of the liquid is pushing down on you which makes pressure rise.
The instruction booklet for your pressure cooker indicates that its highest setting is 11.4 psi You know that standard atmospheric pressure is 14.7psi so the booklet must mean 11.4 psi above?
Yes, that's correct. Pressure cookers work by increasing the pressure above atmospheric pressure to cook food faster. In this case, the pressure cooker can increase the pressure inside to 11.4 psi above the standard atmospheric pressure of 14.7 psi.
What layer is solid due to tremendous pressure?
A layer that is solid due to tremendous pressure is the inner core of the Earth. The inner core is mostly composed of iron and nickel, and the immense pressure from the layers above prevents it from melting despite its high temperature.
Earth's core is under great pressure due to?
the tremendous weight of the layers of rock and metal lying above it. The high temperatures and extreme pressure conditions within the core are caused by the gravitational forces acting on the mass of the Earth.
Why aren't deep sea fish crushed by the earth to Miranda pressure of the water above them?
Some creatures have adapted to living in the great pressure found in the depths of the oceans. If they are brought up to the lesser pressure at the surface, they don't usually survive.
When deep sea fishes are brought up to the surface of the sea their bodies burst why?
The lower you go in the sea, the greater the water pressure, because of all the water above you, pressing down with its weight. To avoid being crushed by the water pressure, fish have an internal body pressure that is equal to that of the external water pressure. When the fish are raised to the surface rapidly, their internal pressure then is much greater than the air pressure, and it can cause their bodies to burst. If they are raised more slowly, the pressure has a chance to equalize. (Exactly the same reasoning to explain why an astronaut's body would burst if he forgot to get into his space suit before he stepped out on the veranda and began a space walk.)
Are there any animals that have their mouths above their eyes?
NO there is no animal that have their mouth above their eyes
Why do one not crushed under the weight of air above us?
The air pressure inside our bodies matches the air pressure outside, so there is equilibrium. Our bodies are also designed to withstand the pressure exerted by the weight of the air above us through structural integrity and the balance of internal and external pressures.
Is there fishes in Victoria falls?
There are 39 species below the Falls and 89 above the Falls
The pressure above a liquid in a sealed container is?
equal to the sum of the atmospheric pressure and the pressure due to the weight of the liquid above the point of interest.
What is a sentence using the word tremendous?
The cat was absolutely tremendous.He was a tremendous actor.The tremendous robot won the building competition.And it would likely be a tremendous decrease from what one would make in industry. That's one of the reason we've got a new program executive officer and a tremendous amount of focus. He possesses tremendous hands and a knack for getting open, while his speed is above-average for his position.And his tremendous gifts as a singer and arranger, and as a synthesizer of world music in a pop context, became calcified.When an average-size car travels down the freeway, it uses tremendous amounts of energy to displace air.
When intrapulmonary pressure is above atmospheric pressure what is able to occur?
When intrapulmonary pressure is above atmospheric pressure, air will move out of the lungs due to the pressure gradient, allowing for expiration. This is known as exhalation.
How do creatures bear high pressures in the oceans?
They have evolved to deal with it by exerting an equal amount of pressure outwards as the average amount of pressure that is pressing down on them from above. Humans have done the same, since we are bearing the weight of the entire atmosphere but never notice! Internally, we are exerting the same pressure outwards to balance it. Certainly this is not as much as at the bottom of the ocean, but without this mechanism we would be crushed.
Why does pressure drop as you travel upward from earth surface?
Air pressure is caused by the weight of the atmosphere above an object. When one goes higher, there is less air above and so the pressure drops.
