What role does atmospheric pressure play when someone is drinking a liquid through a straw?

when you drink through a straw you remove some of the air in the straw. because there is less air the pressure of the straw is reduced. but the atmospheric pressure on the surface of the liquid remains the same. henceforth how it helps you drink

∙ 11y ago?? Drinking lemonade cannot change the air pressure. Are you perhaps wondering how air pressure HELPS you drink lemonade through a straw? When you suck on the straw, you are are not PULLING the lemonade up into your mouth. You are reducing the air pressure inside the straw and atmospheric pressure, the weight of the air, is PUSHING the lemonade up the straw to fill the vacuum you created.

∙ 12y agoThe Air pressure goes down in the straw because you are sucking the the air in the straw into your lungs. Once the air pressure goes down the liquid goes up the straw to fill in the missing space created by the air going from the straw into your lungs

Explain why drinking through a straw shows that fluids flow from areas of high pressure to areas of low pressure?
Because your sucking
How does atmospheric pressure distribute energy around the globe?
Changes in pressure cause wind to blow. This facilitates some energy transfer through the atmosphere through eddy propagation, for example, this also facilitates the movement of air masses and cyclones across latitudes.
What are convection currents created by?
Convection currents are the flow of fluid (liquid or gas) caused by the molecular motion resulting from the transfer of heat through the fluid. In meteorology it is the vertical movement of atmospheric gases caused by heat, atmospheric pressure, condensation of water vapor, and other factors.
The greatest atmospheric instability occurs in an air mass that is?
Atmospheric instability is a condition where the Earth's atmosphere is unstable due to a high degree of variability through distance and time. The greatest atmospheric instability occurs in an air mass that is warm and moist.
Where do low pressure systems occur?
Well the answer is quite simple when you understand it. A low pressure area, or "low", is a region where the atmospheric pressure at sea level is below that of surrounding locations. Low pressure systems form under areas of wind divergence which occur in upper levels of the troposphere. The formation process of a low pressure area is known as cyclogenesis. Within the field of atmospheric dynamics, areas of wind divergence aloft occur in two areas. The first area is on the east side of upper troughs which form half of a Rossby wave within the Westerlies (a trough with large wavelength which extends through the troposphere. A second area of wind divergence aloft occurs ahead of embedded shortwave troughs which are of smaller wavelength. Diverging winds aloft ahead of these troughs cause atmospheric lift within the troposphere below, which lowers surface pressures as upward motion partially counteracts the force of gravity.GOOD LUCK!
How is pressure related to drinking through a straw?
"Muscular action reduces air pressure in the mouth, whereupon atmospheric pressure forces the drink up the straw." ~ Wikipedia
How does air pressure help drinking through a straw?
when you drink through a straw you remove some of the air in the straw. Because there is less air pressure of the straw is reduced. But the atmospheric pressure on the surface of the liquid.
How is sound transmitted to the eardrum?
Sound is transmitted through the air to the eardrum as variations in pressure above and below ambient atmospheric pressure.
When cold air moves into an area the atmospheric pressure is?
When cold air moves into an area, the atmospheric pressure is high because cold air is denser than warm air. When a cold front moves through an area, the pressure always rises.
How is drinking through a straw related to vacuuming?
It is simply creating a low pressure
How fast is 343 ms?
343 m/s is the speed of sound through air at regular atmospheric pressure.
As soon as the intake valve opens what forces air through the carburetor and manifold to fill that vacuum?
Atmospheric pressure
Why do a weather balloon keep increasing in volume as it rises through the stratosphere?
As it goes higher, the atmospheric pressure decreases.
Why do balloons expand as they rise through the troposphere?
The ballon contains a fixed amount of gas producing internal pressure. At the surface, this pressure equals the surface atmospheric pressure. As the balloon rises, the atmospheric pressure drops, allowing the balloon to expand, keeping the internal pressure and external pressure equal. If the balloon is fully inflated at the surface it will burst at higher altitude.
How is a person able to drink using a straw?
Because he creates lower air pressure in his mouth compared to the atmospheric pressure - thus the liquid is pushed through the straw as a result of pressure difference.
