I do know water is the most amazing material in the world. It is the only material that when it gets warm it expands and when it gets cold it expands too. Right around 4 degrees C it is the densest it can be.

In your case it can be like the glass of water next to your bed where the dissolved air is changing state from solid to a gas.
