Question

water is a universal solvent because it... floats when frozen dissolves most substances it can be found anywhere it freezes when it gets cold

Explanation:

To determine why water is a universal solvent, we analyze each option:

• "floats when frozen": This is about water's density in solid form, not its solvent property.
• "Dissolves most substances": The definition of a universal solvent is a substance that dissolves a wide variety of solutes, so this matches.
• "It can be found anywhere": Ubiquity doesn't define its solvent ability.
• "It freezes when it gets cold": This is about its freezing point, not solvency.

Answer:

Dissolves most substances
