Can oil and water mix in outer space?

Question

If the lack of pressure doesn't split everything apart and the cold temperature doesn't freeze the water... could the water and oil mix?

and if they did, could they then freeze together in the cold temperatures? or would that new mixture protect the water parts from freezing thereby producing a gell type of substance?

Answer 1

Good question. Where oil and water are concerned, they will repel each other. This is because water is polar and oil is not. So any such combination will result in two different blobs. I would also guess that the water will form a blob *inside* of the oil. I say this because the molecules of water have a weak attractive force for each other while the oil molecules don't. So the water would tend to pull together, forcing the oil out.

Where weightlessness helps is in the mixing of materials which are different only in density, like lead and aluminum. Or two types of substances which are non-polar.

Answer 2

yes at zero gravity,there is a probability of mixing of water and oil.
by pascal's law,at zero gravity,all types of liquid will exert same pressure equally on all sides.
practically they are making emulsion by mixing oil and water by adding some substance.
so,they can mix at suitable condition.
i will say u something ,u do it:
take water in a glass and mix oil with it and keep it in freezer
and see what happends.
best of luck!

Answer 3

I do not think they would intermix no matter what the gravity situation, They are naturally opponents that will not mix,
You may ask this in chemistry to see if such a thing can happen, Im no chemist and can not give an educated answer,

Answer 4

Basic chemistry says that they will repel each other no matter what the gravity.
