Question

When you put soda in a glass why is there a stream of bubbles coming vertically out? How does it happen? Why? Oh and don't say because of Carbon dioxide.

Answer 1

Just because of Co2 *

Answer 2

I believe its due the the density of co2... its less dense than the liquid around it, so it rises up to the surface.

Answer 3

When the soda is put in the bottle high pressure carbon-dioxide is injected into it and the bottle sealed. When the cap is removed the high pressure dissolved gas will move to low pressure, bubbles form and they are less dense than the soda. The density difference exerts a buoyancy force on the bubbles, pushing them against gravity, (the liquid falls to the bottom)

Answer 4

Why isn't it irregular? Why does it come up in a vertical line?

Answer 5

The force of gravity is towards the center of Earth, ie down.
The liquid moves in this direction
The buoyancy of the gas bubbles is to allow the water to get to the bottom, the quickest way to do this is for the bubbles to move the opposite direction to the gravity; ie down
