When you open a bottle of carbonated cola you see bubbles of gas bursting from the surface. What can you infer about the amount of gas dissolved in the solution before you opened the bottle?
If gas comes out of solution when a bottle is opened, then there must have been a greater amount of dissolved gas in the substance while it was under pressure prior to opening the bottle.
What will help a gas stay dissolved in a solution?
you could increase the pressure of the surrounding atmosphere like in a cola bottle
Which gas escapes rapdily as we open a bottle of cola?
The gas to create bubbles in the cola is carbon dioxide.
Which is heavier a bottle of fizzy cola or a bottle of flat cola?
A bottle of fizzy cola is heavier. Weight is related to mass. Whenever something loses material and doesn't gain any to replace it, it loses mass. The bottle of fizzy cola has everything the bottle of flat cola has, but the bottle of flat cola has lost some carbon dioxide. Although carbon dioxide is a gas, and doesn't weigh much more than air, the carbon dioxide in cola is compressed and dissolved and is at a higher pressure and density than carbon dioxide at normal atmospheric pressure. Therefore there is a greater mass of it present. However, the difference in weight would still not be great between the fizzy cola and the flat cola, and it would be difficult to detect.
What 2 conditions are needed to keep carbonated water(a gas) dissolve in coca- cola?
what 2 conditions are needed carbonated water (a gas) dissolved in coca -cola
Why does a balloon inflate when sealed over a bottle of coca cola?
The cause is that Coca-Cola release carbon dioxide gas.
What happens to the gas when you take the lid off a bottle of Coca Cola?
The carbon dioxide gas in solution (added under pressure) begins to diffuse into the air, and eventually most will escape, leaving the beverage flat (uncarbonated). If you unwisely agitate (shake) the cola before opening, the gas molecules will gain energy and will more quickly diffuse from the open bottle: the cola will explosively gush out of the bottle with it.
What is the fizz in coca cola?
The fizz in Coca-Cola, like all carbonated drinks, comes from dissolved carbon dioxide in the liquid. Upon opening the container, the internal pressure drops, causing the dissolved gas to escape.
When a warm bottle of cola is opened and gas spews is it a physical or chemical change?
When a warm bottle of cola is opened and gas spews out, it is a physical change. The release of gas is due to a change in pressure causing the carbon dioxide already present in the liquid to rapidly escape. No new substances are formed in this process.
Why does a flat sealed bottle of fizzy drink when shaken expand the bottle when no new air has got in?
When a fizzy drink is shaken, the carbon dioxide gas that is dissolved in the liquid gets released. This increases the pressure inside the bottle, creating more volume and expanding the bottle. The gas pushes against the bottle walls, causing the expansion.
What does cola have in it?
Cola drinks contain carbonic acid (dissolved carbon dioxide gas) and many also contain phosphoric acid (and/or lactic acid) to balance the sweet taste.
Does Coca-Cola dissolved meat?
no.
