What happens as you move higher in the tropospere?
Atmospheric pressure falls
What is the pressure difference between the external air and the pleural cavity when inhalation just begins?
In inspiration, intrapulmonary pressure drops 3mm/Hg below atmospheric pressure and air flows into the lungs.
In general as elevation increases from the ground up what happens to atmospheric pressure?
Pressure decreases. This is because atmospheric pressure is a measure of the weight of the atmosphere weighing down. If you are high in the atmosphere, much of the atmosphere is below you so the pressure from above will be very small.
What is Neptune's atmospheric pressure compared to earth's atmospheric pressure?
42% higher
What happens to the air pressure and wind speeds in a hurricane in a category 4 or 5?
Air pressure drops and wind speed increases.
When intrapulmonary pressure drops below atmospheric pressure what is able to occur?
Inspiration occurs when the intrapulmonary pressure decreases to below atmospheric pressure
What happens to atmospheric pressure as you climb a mountain?
it decreases
What happens to the atmospheric pressure when weather is fair?
it dies
What happens at a substance's boiling point?
Its vapor pressure equals atmospheric pressure.
What happens when you go up into the atmosphere?
The atmospheric pressure reduces
What happens as you move higher in the tropospere?
Atmospheric pressure falls
What happens to atmospheric pressure as you move up away from sea level?
As altitude above seal level increases, atmospheric pressure decreases.
What happens when pressure greater than atmospheric pressure is applied to pure water or a solution?
If a pressure greater than atmospheric pressure is applied to a solution or pure water, its water potential increases
When intraalveolar pressure exceeds atmospheric pressure what happens?
intrapleural pressure exceeds atmospheric pressure, but lungs don't collapse because intra-alveolar pressure increases, too (4 mmHg pressure gradient stays same)
What will happens to us if we go seventeen meters underwater?
We will experience a pressure 2.7 times atmospheric pressure.
What happens to air pressure when the temperature drops?
When air pressure drops temperature also drops. Thus on high mountains low air pressure is accompanied by low temperature. This is true for high atmosphere also.
What happens when pressure is lower inside the lungs than outside the lungs?
atmospheric
