Julie takes a cold glass of clear, colorless liquid out of the refrigerator and puts it on the table. as the liquid warms up to room temperature, julie sees bubbles of gas form in the liquid and rise to the surface. which conclusion is best supported by julie’s observations?

The bubbles indicate that there is a gas dissolved in the liquid, which may remain dissolved when the liquid is very cold, inside the refrigerator.

When the temperature of the liquid increases, it reduces its ability to dissolve the gas and the gas escapes (bubbles) from the liquid.

At the end, the behavior of the liquid permits  you to conclude that the  liquid is a mixture because it has a gas dissolved in it.

What do you not know about it
