Investigation Observations After Two Liquids Are Combined The temperature of the combined liquids increased, and a solid substance formed. The temperature of the combined liquids decreased, and bubbles formed. One liquid settled to the bottom of the beaker, and the other liquid rose to the top. 3. The combined liquids turned from clear to a bright purple.
