bubbles in a vacuum?

Question

is it possible to create bubbles in a container that contains liquid only(i.e. no air) when u shake it?
thanks

Answer 1

Yes actually you can. It's called cavitation. There is a kind of shrimp that uses this to attack its prey.

Answer 2

In a container that contains only liqiud and is at atmospheric pressure, you can create bubbles when you shake it if the air or gas that will form the bubbles have been injected into the liquid under pressure before putting the liquid into the container...pour soda pop into a container and wait till all the bubbles are gone, and then shake it and more bubbles will form because some of the gas is still contained in suspension in the liquid......In a vacuum, a liquid cannot exist. It will vaporize.

Answer 3

Interesting question. I tried it using a plastic syringe and some water mixed with dish soap. It produced a lot of foam even after creating a vacuum.
But the problem is that I can't get the air out completely because there is some air dissolved in the water that is released when I decrease the pressure. And even if you get all the air out you won't get a real vacuum because some of the water will evaporate and turn into a gas. But I don't think bubbles can exist in a true vacuum because in a bubble you have 2 forces. The surface tension pulling the bubble together and the inside pressure preventing it from collapsing. Without any gas in the inside the bubble will collapse from the surface tension.

Answer 4

In a vacuum all liquids will boil. If you doubt it, you will find out by seeing that the higher you go in elevation, the lower the boiling point.
This pattern is clear until you make it in to space. At that point water is either ice, or it is boiling away.

Answer 5

no because the pressure and heat to create the bubles would be very high i cant think of a liqiud that that wants to evaporate into a gas that bad and create bubbles
