More about this volume later. Gas molecules in the neck bop around at high speeds over kilometres an hour. Some hit the liquid below and enter the soda. Other gas molecules dissolved in the soda escape into the neck region.
The concept of equilibrium. Gradually, the rate at which gas molecules leave the neck and enter the soda equals the rate they leave the soda for the neck, and the soda is in equilibrium. The bottle achieves an equilibrium state after bottling and later on the shelf. How much carbon dioxide gas is in the bottle Henry's Law. The bottle temperature is constant; the gas is in equilibrium and the bottle contains a given gas-soda combination - namely the bottled soda. So we can apply Henry's Law, which says that in this case, the amount concentration of dissolved gas in the soda is proportional to the pressure of the gas in the bottle's neck above the soda.
Since the neck gas pressure is double the atmospheric pressure, the bottle contains double the concentration of carbon dioxide gas as it would at one atmosphere - that is, two bottles of carbon dioxide gas.
Why the capped, quiescent bottle has no bubbles. The bottle has been sitting on the shelf for some time. We look at it and see no bubbles, because bubbles can only exist if their pressure is at least as great as the surrounding liquid.
It takes work to make a bubble. But, since the bottle is in a state of relative rest, the pressure is the same the bottling pressure of two atmospheres all over, so no bubbles can form. How bubbles form when you shake the bottle. You might think the pressure inside the bottle increases when shaken, but it does not. Something else causes the eruption of foam. Find out by a simple experiment.
Stir a glass of soda with a spoon, and create a small whirlpool. There's a string of bubbles in the vortex. That's the mechanism. We all know Coca Cola is laden with sugar and that, at a push, you could use it to clean your toilet. But it's a bit of a mystery as to what it does to your body.
The brains behind website The Renegade Pharmacist has revealed exactly what a refreshing can of Coke does to your system within the first hour of drinking it. And it's not pretty. You don't immediately vomit from the overwhelming sweetness because phosphoric acid cuts the flavour, allowing you to keep it down.
Your blood sugar spikes, causing an insulin burst. Your liver responds to this by turning any sugar it can get its hands on into fat. Caffeine absorption is complete. Your pupils dilate, your blood pressure rises, as a response your livers dumps more sugar into your bloodstream.
Does Coca-Cola have the same effect on brain chemistry as heroin? Does phosphorus bind calcium, magnesium, and zinc? Phosphorus does indeed bind to calcium, magnesium, and zinc, making it difficult for your body to use these necessary nutrients. Phosphorus is found naturally in many healthy foods, including dairy and whole grains. It is concentrated in much greater amounts in soda, and if not balanced out with enough dietary calcium, this can lead to weakened bones.
One study found that women who consumed cola-type soft drinks including regular and diet versions had lower bone mineral density than those who had less than one cola per month.
