If a pressure greater than atmospheric pressure is applied to a solution or pure water, its water potential increases
Pressure differentials are a cause of structural movement. Since the human body's internal pressure is basically that of atmospheric pressure, the human body experiences no change in structure. When the human body is exposed to vacuum pressure such as in space, the human bodies pressure would exert a force greater than that of the vacuum resulting in the human body to expand...(and explode ). When submerged beneath the ocean at great depths, the human body's internal pressure would not be enough to "push" against the force of the water and would implode...
Hypotonic
A hypertonic environment with regard to the cell.
A solution in which the salt concentration is greater outside the cell than inside the cell is known as
If a cell containing 97% water was placed in a hypertonic solution of 10% salt and 90% water, then the cell would crenate. This occurs due to osmosis. The hypertonic solution will pull out the water which will cause the cell to shrink. It does this to reach equilibrium but equilibrium cannot be attained. The concentration of the hypertonic solution is too great for the cell or Isotonic so the permeable cell will give to the osmotic pressure being greater than turgor pressure; solute and waste will be removed from the cell causing it to shrink in size because the turgor pressure keeps the cell stable.
It is compressed and occupies a smaller volume.
It is greater.
Earth's atmospheric pressure is measured as 1 bar. Jupiter's atmospheric pressure is 100 million bars. Therefore, it is 100 million times greater
Because while atmospheric pressure is the greater of the two the vapour pressure of the water can not spontaneously form bubbles (ie boil).
when atmospheric pressure is greater than the pressure within the lungs, inspiration occur.
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
it is a region where the atmospheric pressure at the surface of the planet is greater than its surrounding environment.
Yes, but only at greater than standard atmospheric pressure.
Low. High on the bottom low on the top creating lift. The faster the airflow the greater the pressure difference and the greater the lift.
A high pressure zone. Site of clear skies and warm weather.
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?
Blood pressure is the blood flow when the heart is pumping (top number) and when the heart is resting (bottom number). The body is a closed system and requires enough blood pressure to pump the blood throughout the body. A typically healthy blood pressure would be 120mmHg/70mmHg. Atmospheric pressure is the weight of the atmosphere at a specific location and altitude. At sea level, atmospheric pressure is 760mmHg. So actually, atmospheric pressure is much greater than blood pressure. Most people never have to worry about atmospheric pressure affecting blood pressure. However, deep sea divers experience an increase in blood pressure while diving, and astronauts experience a decrease in blood pressure when in space.
