Opening a soda can/bottle is a physical change. A good way to figure this out is to ask- can the change be reversed? Soda is formed when carbon dioxide (CO2) gas gets mixed with the flat soda to cause the bubbly fizz. When soda can is opened the pressure causes the CO2 to create an explosion of bubbles. Soon after the soda 'calms down' it eventually becomes flat. this flat soda can once again be 'injected with carbon dioxide to become bubbly.
Physical - it can return to its original state, and go back to having fizz (if you stir it or shake it up). If the soda sits open in the refrigerator or on the counter for a while, it will lose its carbonation, and therefore go through a chemical change.
Nope. The pressure keeps the Carbon Dioxide dissolved in the liquid, and when that pressure is relieved, the CO2 rapidly returns to its gaseous state. None of the molecules are reacting or changing, although the CO2 switches from aqueous to gaseous phase.
Physical change. The sugar just well..."dries" out.
It's a physical change because you still end up with soda, it hasn't changed into something else. You cant get it back to its original bubbly state, but it is still soda.
"is a glass of coke that goes physical or chemical change?" i think its chemical change. because, i think when we drink them..we cant bring them to their original shape..it will just pissed off m not sure but.. i think its goes widh chemical ^_ _ _ _ _ ^ "is a glass of coke that goes physical or chemical change?" i think its chemical change. because, i think when we drink them..we cant bring them to their original shape..it will just pissed off m not sure but.. i think its goes widh chemical ^_ _ _ _ _ ^
Its a physical change as there is no reaction.

No the brand of the soda does not have any affect over the speed of how fast a soda goes flat.
Physical
Yes, it is a physical change.

Soda freezing in the freezer is a physical change and not a chemical change. This is because the liquid is only changing into a solid.

Crushing is a physical process.
