Hey Komati,
It's good that you provided some explanation of your thought process here, but in the future, please write only in complete, grammatical sentences with correct spelling. This is both good practice for the essay section, and also allows me to actually understand your logic. Truthfully, I don't follow what you're saying here.
In this sentence, we know the scientists are trying to reduce the mixture's tendency to vaporize. That means the word in the blank should just describe a mixture that DOES tend to vaporize.
Both "volatile" and "unstable" imply something that could switch between forms (liquid to gas/vapor), so those are the words we want.
-t
P.S. You seem to be going into the idea that we WANT a mixture in liquid form. We don't want anything. This is a pure vocab question, not reading comprehension, so "want" is not relevant. The SCIENTISTS want the mixture not to vaporize, but currently it does, and the blank simply describes this mixture that tends to vaporize.
-t
