Why does the liquid move into the siphon when air is removed from the siphon by the pipette?
When air is removed from the siphon by the pipette, the atmospheric pressure pushes the liquid into the siphon to fill the vacuum created. This creates a pressure difference between the two ends of the siphon, causing the liquid to flow into it.
Why atmospheric pressure varies with height in a different way from the way liquid pressure varies with depth.?
For the same reason. The liquid above the location considered, or the atmosphere above the position considered, helps contribute to the pressure; if there is more liquid or atmosphere above, there is more pressure.
When you drink with the help of a straw what forces the liquid up the straw?
When you suck on a straw, you create a vacuum in your mouth, and the atmospheric pressure pushes the liquid up the straw and into your mouth. The difference in pressure between the area inside the straw and outside is what causes the liquid to move upwards.
In a homemade barometer why did the straw move up and down?
The straw moved up and down in a homemade barometer due to changes in atmospheric pressure. When the pressure increased, the liquid in the bottle pushed the straw up. When the pressure decreased, the straw moved down due to the weight of the atmosphere pressing down on the liquid in the bottle.
Can atmospheric pressure affect an object's velocity?
Yes, atmospheric pressure can affect an object's velocity. Higher atmospheric pressure can create more air resistance, which can slow down the object. Conversely, lower atmospheric pressure can result in less air resistance, allowing the object to move faster.
What device can use atmospheric pressure to move a liquid from one side of a pile of rocks to another?
siphon
How does atmospheric pressure change as you move away from the surface of earth?
Atmospheric pressure decreases as you move away from the surface of the Earth. This is because the weight of the air above you decreases with higher altitudes, resulting in lower atmospheric pressure.

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.
When you drink with the help of a straw what forces the liquid up the straw?
When you suck on a straw, you create a vacuum in your mouth, and the atmospheric pressure pushes the liquid up the straw and into your mouth. The difference in pressure between the area inside the straw and outside is what causes the liquid to move upwards.
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.
As you walk down a mountainside atmospheric pressure will what?
It will increase. Atmospheric pressure decreases with altitude and increases as you move toward sea level. At sea level, atmospheric pressure = 1.0
In a homemade barometer why did the straw move up and down?
The straw moved up and down in a homemade barometer due to changes in atmospheric pressure. When the pressure increased, the liquid in the bottle pushed the straw up. When the pressure decreased, the straw moved down due to the weight of the atmosphere pressing down on the liquid in the bottle.
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).
Can atmospheric pressure affect an object's velocity?
Yes, atmospheric pressure can affect an object's velocity. Higher atmospheric pressure can create more air resistance, which can slow down the object. Conversely, lower atmospheric pressure can result in less air resistance, allowing the object to move faster.
