Why it is difficult to drink liquid with straw on the top of the mountain?
Barometer
It would be more difficult to drink with a straw on the top of a mountain because of low atmospheric pressure. You would not have as much pressure to push the drink up the straw.

What happens when you drink through a straw?
This question points up some key misconceptions about what a vacuum is.So you put a straw in your cup of water. If you look down the straw or could look through it, you would see that the level of water inside and outside the straw are exactly the same. This is because the atmosphere is pushing down on the water inside the straw, and it is pushing down equally hard on the water outside the straw. So the pressures are equal.When you suck on the straw, you are decreasing the pressure in your mouth and lowering the pressure of the air in the top of the straw. When that happens, the force of the atmosphere pushing on the water in the glass is higher than the force of gas inside the straw. The atmosphere forces the liquid up the straw into your mouth. So, in essence, you ARE NOT sucking the liquid into your mouth, the atmosphere is pushing it there.This is easily proved by an experiment. Try drinking water from a straw that is more than 20 meters tall. It won't work. At around 20 meters, the massive column of water inside the straw would be pulled down by gravity, with a force greater than the upward force caused by the atmosphere. Even if you completely evacuate the straw with a high-powered pump the water won't make it up the straw. This is why you can't pump water out of a well that is more than 20 meters deep in the ground. Anything deeper than that and you need to use a compressor to pump air at high pressure down into the well, to force the water out (essentially make the upward pressure higher than the atmosphere alone provides), or revert to the tried and true method using buckets.Of course, a similar principle applies with underground or artesian wells. The water there is already under greater pressure and will flow to the surface if given a path.
When measuring a small quantity of liquid which instrument would permit the most accurate reading?
If available, a small, glass graduated cylinder would be best. Next best would be a test tube or any clear or semi-transparent cylinder/ small plastic recycled container/bottle. If an eyedropper is not available, recycle a milkshake straw to move/transfer small quantities of a liquid. Place the bottom end of the straw in the liquid almost to the bottom. Then hold your thumb tightly to the top end of the straw and lift out of the liquid. When you remove your thumb the contents will spill out of the bottom of the straw.
What force is drinking out of straw?
It is all to do with air pressure. We lower the air pressure inside the straw by sucking the air out of it, atmospheric pressure which is pushing down on the surface of the drink literally forces it up the straw into our mouth.
What Chianti has straw around the bottle?
Chianti Classico Raffino had the straw around the flask
Which are demonstrated by water moving up a straw?
The power of suction is what is demonstrated by water moving up a straw. When you suck through a straw, the water has nowhere to go but up.
Why is it difficult to drink liquid with a straw with holes in it?
because when you suck up the liquid, it will just go right through the holes.
When you drink a soft drink with the help of a straw what forces the liquid up the straw?
Suction.
How is it possible to drink liquid by a straw?
Suction.
Will it be easier to drink out of a straw from on top of a mountain or in new Orleans?
It will be easier to drink out of a straw from the top of a mountain than from New Orleans. This is because gravity has a stronger pull downward at New Orleans.
Why can't we suck a cold drink through a straw on the moon?
we can not drink cold drink through straw at moon because moon has no atmosphere to exert pressure on liquid
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 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.
Would it be more difficult to draw soda through a straw at sea level or on top of a mountain?
top of a mountain
What is slightly more difficult to draw soda through a straw at sea level or on top of a high mountain?
high mountain
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 can you drink through a straw?
because there is a gap throgh it therefore liquid can pass through it (:
Why can't you drink through a straw in a sealed container?
To drink from a straw you need an opening for the atmospheric pressure to push into so it can displace the amount of liquid you are sipping in. Without an opening it is near impossible to suck the contents out because there is no pressure helping you displace the air then liquid you are trying to suck out of the straw.
