Why atmospheric pressure not acting on the living organisms?
I believe that you mean to ask why the atmospheric pressure of 24 pounds per square inch does not crush living organisms. That pressure exists both inside and outside of living organisms; air is inside us as well as outside, since we inhale it. And the parts that have no air are permeated by water, which is relatively incompressible. An organism would only feel the air pressure as a crushing force if it had a section of its body which contained a vacuum, and there is no living organism which does.
If the air pressure inside a container were greater than the fluid pressure outside the container what would happen?
Okay i think i might know but i'm not sure but i think this can never happen because if it did the atmospheric pressure would crush us. our fluids in our bodies exert pressure on the atmospheric pressure(the same amount) and pretty much neutralize the effect!
Why is air pressure inside a home greater than outside air pressure on a cool day?
If the building is not air tight the presure should be just about the same inside or outside. If all the doors and windows are shut and you turned on the heat, the presure may be slightly higher inside.
What is the air pressure inside a papper bag?
The air pressure is the same, inside or outside the paper bag.
What is the pressure cooker also called?
A pressure cooker is a cooking vessel that is enclosed with a lid that seals to the pan with a rubber gasket, which cooks at a pressure that is higher than the atmospheric pressure. These cookers are usually made of thick-wall stainless steel or thick aluminum. In the lid is a small vent-hole that contains a pressure-regulating mechanism. Water in the food being cooked will boil and cause a steam build-up in the vessel, which will increase the pressure inside the vessel. The pressure-regulating mechanism on the vent-hole will allow some steam out if pressure exceeds a certain limit (usually around 15 psi, or 15 pounds per square inch), thus maintaining a more or less constant pressure inside the pressure cooker that is higher than atmospheric pressure. Since the boiling point increases with higher pressure (for example, water boils at 100 degrees C at atmospheric pressure but it will boil at a higher temperature inside a pressure cooker since the pressure inside is higher), the temperature inside a pressure cooker can rise more than it would have in an open-enclosure pan. Because of the higher temperature, meat becomes soft easily and food cooks faster causing less loss of nutrients. Pressure cookers often have various safety mechanisms to prevent the buildup of excessive pressure and exploding. After cooking is finished, it is important to release the steam slowly first, because if the lid is opened suddenly, a large amount of steam escaping can cause scalding. Many pressure cookers have special mechanisms for controlled steam release before opening the lid.
When the water level is higher inside than outside the flask is the gas pressure in the flask higher or lower or the same as the atmospheric pressure?
The gas pressure in the flask is lower than the atmospheric pressure when the water level is higher inside than outside the flask.
Why do the sides of a flexible container collapse when the air is removed?
A pressure difference is created, low pressure on the inside and higher pressure on the outside (the atmospheric pressure). The atmospheric pressure crushes the plastic container, acting on the outer plastic walls.
What happens when pressure is lower inside the lungs than outside the lungs?
atmospheric
Why does a difference in air pressure crush things?
A can or container can stay rigid due to equal pressure from the inside and the outside. When the atmospheric pressure from the outside increases mote than the pressure pushing out from the inside, the material gets crushed.
How would you demonstrate the presence of atmospheric pressure?
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.
Is the pressure inside the balloon equal to the atmospheric pressure?
Think about this: if the pressure WERE equal, what would happen in the instant when you open the neck of the balloon and whatever pressure is on the inside meets the pressure that is on the outside (atmospheric pressure)? In your experience, what DOES happen?
How does atmospheric pressure change as you move up away from sea level?
as you move up from sea level, the atmospheric pressure decreases. At higher elevations, theres less air above you so therefor less air pressure. When the air pressure outside your body decreases, the air pressure inside also decreases (slowly).
What exactly is compressed air?
Air that is held inside one of several types of special containers at a decreased volume is known as compressed air. For the air to be compressed, its pressure inside the container must be at a higher pressure than that of the atmospheric air outside of it.
Why does the lung collapse if intrapleural pressure is not maintain?
Inspiration happens when the pressure inside the lungs is lower than the atmospheric pressure (outside) and air rushes into the lungs. Expiration is when the air inside the lungs is higher than the atmospheric pressure and the air rushes out of the lungs. If the intrapleural pressure (pressure within the pleura of the lungs) isn't maintained then the pressure in the lungs can't differentiate between inspiration and expiration and so the lung collapses.
The air pressure inside the can compare to the air pressure outside the can equal lower or higher?
There is no difference of the average local air pressure inside or outside of the headphone.
If the pressure inside a car tire is equal to atmospheric pressure the tire is flat why?
If inside and outside same pressure that means there is no pressure. The added pressure is what blows the tire up like a balloon and holds the weight of the car up.
What is the pressure inside the pressure cooker when closed but no heating will it be equal to atmospheric pressure or not?
The pressure inside will be the same as what the atmospheric pressure was when the lid was closed as long as no heat is added or removed.
