Water rises up a straw due to capillary action, which is the result of adhesive forces between the water molecules and the material of the straw. This causes the water to climb up the walls of the straw, against the force of gravity.
The straw will displace the water, causing the water level inside the straw to rise slightly. When you suck on the straw, you create a vacuum inside it, pulling the water up into the straw and allowing you to drink it without tilting the cup.
When the water in the bottle is cooled, it contracts and creates a lower pressure inside the bottle. The higher atmospheric pressure outside the bottle pushes the water up through the straw to equalize the pressure, causing the water level in the straw to rise.
When a straw meets water, the water molecules are attracted to the straw due to the force of surface tension. This attraction pulls the water up the sides of the straw, causing it to bend as it follows the shape of the straw.
When you suck on a straw, you decrease the air pressure inside the straw, creating a partial vacuum. The higher air pressure on the surface of the liquid outside the straw then pushes the liquid up the straw and into your mouth.
The liquid moves up the straw due to air pressure. When you suck on the straw, you create low pressure inside the straw. The higher air pressure outside the straw then pushes the liquid up to balance the pressure difference.
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.
Surface tension is related to the cohesive properties of water. Capillary action however, is related to the adhesive properties of water. You can see capillary action 'in action' by placing a straw into a glass of water. The water 'climbs' up the straw. What is happening is that the water molecules are attracted to the straw molecules. When one water molecule moves closer to a the straw molecules the other water molecules (which are cohesively attracted to that water molecule) also move up into the straw. Capillary action is limited by gravity and the size of the straw. The thinner the straw or tube the higher up capillary action will pull the water.

When you put a straw in a water bottle I think the straw stinks and then when you let go of breathing in the water bottle I think it increases and then after that I think when you boil water and then you put the straw in the bottle and put the boiling hot water in the bottle and then I think the straw is like cutting it thanks for reading this but I think it's the wrong answer sorry if it is
Capillary action is the phenomenon where water climbs up a straw due to adhesion to the straw's surface, pulling the water along with it. This occurs because the adhesive forces between water and the straw are stronger than the cohesive forces within the water molecules.
When you suck on a straw, you decrease the air pressure inside the straw, creating a partial vacuum. The higher air pressure on the surface of the liquid outside the straw then pushes the liquid up the straw and into your mouth.
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.
The liquid moves up the straw due to air pressure. When you suck on the straw, you create low pressure inside the straw. The higher air pressure outside the straw then pushes the liquid up to balance the pressure difference.
Because you suck it up
The capillary action allows water to climb up sides of a straw due to adhesive forces.
