Removing seed casingsseparating

soda bottle bubbling when openedmixing as before it was opened nothing was happening but as it came in contact with atmosphere it started to bubble.

bright copper statue turning green from weatheringmixing as all vapours and gases in atmosphere combined with copper of that statue they started to change color of statue

removing salt from seawaterobviously removing as one component I.e salt is removed from another substance I.e salt water or salt solution

water decomposingobviously separating as it's constituent elements are removed from compound and converted into individual elements

HOPE IT HELPS !!!

Answer from: martl4175

The correct answer is- A soda bottle bubbling when it is opened.

Soda bottle is prepared when CO₂ ( carbondioxide) is dissolved with H₂O (water) at very high temperature. Thus, it is called mixing.

As we know that solubility is directly proportional to pressure. This means that at very high pressure, CO₂ is soluble but when the bottle is opened at atmospheric pressure, solubility of CO₂ is decreased ( as pressure is decreased). This causes the release of CO₂ in the form of bubbles. Thus, it gets separated in this way.

Thus, soda bottle bubbling when it is opened is an example of mixing and separating.
