How does the last amount of liquid in a straw get into your mouth when the cup is empty and there is no more surface liquid for atmospheric pressure to work on forcing the liquid up the straw?
Air pressure within the straw.
Why a liquid travels up a straw when you suck on it?
1) Air inside the straw moves 2)Pressure inside decreases 3)Pressure of the atmosphere is greater then the Pressure inside the straw=Liquid moves up the straw!!!
When we suck on a straw the liquid travels up. why?
Because of the suction the pressure in your mouth is lower than the atmospheric pressure on the surface of the liquid. This extra pressure pushes the liquid up the straw.
When you drink a soft drink with the help of a straw what forces the liquid up the straw?
Suction.
Why is it possible to suck up liquid with drinking straw?
Basically, you reduce the pressure in the straw. The pressure inside the straw is less than the atmospheric pressure which presses down on the liquid outside.
Why does sucking on a straw make the liquid come up?
When you suck on a straw the pressure at the top of the straw becomes lower than the pressure at the bottom, which forces liquid up.

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 much liquid will a McDonald's straw hold?
A McDonald's straw holds about 12528.1mm cubed liquid. I calculated the density and volume and came up with 12,528.1 milimeter cubed of 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.
What is helps to suck juice from a drinking straw?
The body part that best helps to suck up juice from a drinking straw is the tongue. When a person sucks liquid through a straw, the jaw muscles and tongue work in conjunction to bring the liquid up.
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.
How does a straw work?
As you create a partial vacuum in the top part of the straw, the weight of the entire atmosphere above the glass applies a pressure of 15 PSI on the liquid surface. This pressure pushes the liquid up the straw until the pressure in the straw returns to 15 PSI too. If you keep creating the partial vacuum the air pressure will push the liquid all the way to the top of the straw and out.
