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

?? 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.

The 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

When you drink from a straw the air pressure in the straw is reduced the air pressure on the surface therefore pushes the drink up the straw.

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.

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.
