When you drink with the help of a straw what forces the liquid up the straw?
Air pressure. If you suck, the air pressure of the surrounding air is greater than the pressure inside the straw.
Why does a soft drink rises when sucked with a straw?
As you suck on the straw air is removed from the inside of the straw and the air pressure within the straw is reduced. Once the straw's air pressure is reduced past atmospheric pressure of about 760 mmHg, the Patm forces the drink up the straw and into the sucker's mouth. Gases move from high to low pressure areas until equilibrium is reached.
Can you inflate a balloon in a bottle with a straw sticking out of the bottle why?
Yes you can if all conditions were perfect. By that I mean that the bottle would have to be a near perfect vacuum by sucking out the air from the bottle with the straw. The vacated air from the bottle would be replaced by the baloon stretching to fill the space left by the air. You would have no need to blow into the baloon as the vacuum would do the work for you.
Why does the drinking straw does not drip out when you press the top of the straw with your thumb or finger tip?
Your finger prevents air from entering through the top of the straw. As fluid moves down the straw it leaves a void in it's wake, one that is usually immediately filled by air. By preventing the air from entering the top of the straw, the fluid cannot move downwards because to do so would leave a vacuum space between your finger and the fluid; this "sucks" the fluid back in into place and prevents it from decending down the straw.
Why does a straw hold water if you put your thumb over top of it?
When a thumb is placed over the hole in the top of the straw, it seals the entry way for air. When the straw is pulled out of the water, it is to be noted that a drop or two of water falls out of the bottom but no more falls. This is because when the water droplets fall, this creates more space in the air pocket in the top part of the straw. WIth more space the pressure decrease in the air pocket. In addition, gravity is working on the water inside the straw, but these two forces do not outweigh the force of atmospheric pressure outside, as a result, the water stays within the staw.
How do you drink without swallow so much air?
using a straw
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.
When you drink with the help of a straw what forces the liquid up the straw?
Air pressure. If you suck, the air pressure of the surrounding air is greater than the pressure inside the straw.
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
How does milk rise up when you drink milk from a bottle with a straw?
When you suck from a straw you create a partial vaccuum which reduces the air pressue inside the straw. The air pressure outside the straw pushes down on the milk and forces it up through the straw.
How does a straw work using Boyle's law relating to volume and pressure?
If you suck some air out of a straw, the remaining air in the straw will have to contract in volume in order to maintain the same pressure, which it will do because normal air pressure is still pressing on the liquid in which the straw is submerged. The contracting air will then draw up the liquid.

How does straw function while drink?
When you 'suck' on a straw, you reduce the air pressure inside it. This means the air pressure on the surface of the liquid outside the straw is greater - so it pushes down, which forces liquid up the straw into your mouth.
Are the air bubbles that form on a straw submerged in liquid formed from oxygen that is already in the water or are they carried into the water by the straw as it is submerged?
The straw gives energy to dissolved gases in the liquid, be those gases oxygen, or whatever. The energy given to the gases causes those gases to come out of solution in the water, and to collect on the surface of the straw.
How is drinking from a straw the same as an egg going into a glass bottle?
Drinking from a straw is the same as an egg going into a glass bottle, because air pressure in both cases is used to move something. In the straw, you reduce the air pressure in the straw, so the air pressure around the drink pushes it up into the straw and into your mouth. In the egg, you reduce the air pressure in the bottle, and air pressure around the egg pushes it down into the bottle.
The water in a drinking straw does not drip out when you press the top of the straw with your thumb or finger tip?
there is no air
Why are there air bubbles in liquid?
Air bubbles need a surface to cling to. Believe it or not, the surface of a plastic straw is not as smooth as you might think. You cannot see the roughness of the straw but it is enough for the bubbles to cling to and form there. The surface of a glass is usually smoother than a straw so bubbles have a harder time forming there. They just want to slide up the side of the glass to the top.
