Well even though I don't know this answer, you can always go on more efficient websites also. Answers.com almost always has the correct answer, but some of the questions you people ask, people that are able to do this may not always have the right answer. Maybe ask a friend or a teacher or even your parent to help you find the correct answer. I am sure the answer is somewhere. If it's on the internet or it's in a book, or it's you figuring it out yourself. I am more than positive that you are going to find your answer. I hoped this has helped you! :)
Warm Regards and Thank you for visiting this website! Have a nice day/evening :)

Fizzing is done by the quick escape of carbon dioxide gas from carbonated water (called soda).
Physical because it is changing in the sense that its fizzing your coke was/is coke before and after you opened/shook your can.
No, the fizzing of a warm Coke bottle when opened is not a chemical change; it is a physical change. The fizzing occurs because the carbon dioxide gas that was dissolved in the liquid is released when the pressure is reduced upon opening the bottle. This release of gas is a physical reaction rather than a chemical one, as the chemical composition of the Coke remains unchanged.
A cup of Coke typically weighs around 240-260 grams, including the weight of the cup.
A typical "dime bag" of cocaine would weigh around 0.1 grams, which is equivalent to about 0.0035 ounces.
A cubic yard of metallurgical coke typically weighs around 2,400 to 2,600 pounds (1.2 to 1.3 tons), depending on the density of the coke.
Mixing coke and baking soda will create a chemical reaction that produces carbon dioxide gas, causing fizzing. This reaction is due to the acid in coke reacting with the alkaline baking soda. It is often used as a household cleaner or to unclog drains.
you could disolve salt/sugar into it.
