This is called turgor pressure.
The pressure inside the human body is typically around 760 mmHg (millimeters of mercury) at sea level. This pressure is generated by the weight of the air in the atmosphere pushing down on the body. Changes in pressure can occur during activities like scuba diving or flying in an airplane.
The process that describes the pushing of water across the capillary membrane is called filtration. Filtration occurs due to the pressure difference between the blood inside the capillary (hydrostatic pressure) and the surrounding tissue (osmotic pressure). This pressure gradient forces water and small solutes to move out of the capillary into the surrounding tissue.
Glaucoma is a condition caused by improper drainage of the aqueous humor, leading to increased pressure inside the eye. Over time, this increased pressure can damage the optic nerve and result in vision loss.
Turgor pressure is the pressure exerted on the inside of cell walls when water enters the cell through osmosis. This pressure helps maintain the structural integrity and shape of the cell. If the cell becomes too turgid, it can lead to issues like wilting in plants.
The force exerted by a seedling as it pushes through the soil is due to the turgor pressure created inside its cells. This pressure comes from the water in the vacuoles of the plant cells, causing them to become rigid and push against the cell walls. This pressure helps the seedling elongate and push through the soil.
The pressure inside a balloon is created by the air molecules contained within the balloon pushing against the walls of the balloon. As more air is blown into the balloon, the number of air molecules increases, leading to a higher pressure inside the balloon.
Lowered Pressure
When an inflated balloon is pressed against a wall, the air inside the balloon gets compressed, creating a higher pressure inside the balloon. This higher pressure forces the balloon to stick to the wall due to the imbalance of pressures pushing against the wall.
The air pressure acting on the water surface prevents it from entering the glass. The pressure of the water pushing against the glass is not enough to overcome the air pressure inside the glass, which keeps the water out.
Heating a ball increases the air pressure inside, which causes the ball to inflate. This is due to the gas inside the ball expanding when heated, pushing against the walls of the ball and causing it to expand.
Yes, the air pressure inside a soccer ball affects its bounce. An underinflated ball will have a lower bounce as there is less air pressure pushing against the ground to propel it back up. Conversely, an overinflated ball will have a higher bounce due to the increased air pressure inside.
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.
If the force of gravity crushing a star in weren't balanced, it would collapse. The outward-pushing force counteracting gravity is the energy produced in nuclear fusion, when the heat and pressure inside of stars smashes atoms together.
As the air pressure outside the aircraft decreases, & the air pressure inside the aircraft remains the same, it remains very high inside the aircraft in comparison to the outside, so in the end, the fuselage will explode apart, because the air pressure outside is not enough to counter act it & push against the force of the air pressure inside the aircraft which is pushing outwards.
When a car tire is inflated, the air particles inside the tire collide with the walls of the tire and with each other, creating a force that exerts pressure on the walls of the tire. The pressure builds up as more air is pumped into the tire until it reaches a point where it is equal to the atmospheric pressure pushing back on the tire.
When CO2 is added to a balloon, it has a higher pressure compared to the surrounding air. This pressure difference causes the balloon to expand because the air inside is pushing against the walls of the balloon more forcefully than the air outside.
The difference is that the hard boiled egg can take more pressure. The pressure inside of the egg is pushing outwards so that when you try to crush the egg the pressure is going against you.
