Ice floats in alcohol

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Ice floats only in liquids denser than itself. Ice density is about 0.92 g/cm³ while alcohol (ethanol) density is about 0.79 g/cm³. Since ice is denser than alcohol, it sinks rather than floats.

AI explanation

This statement is false: ice does not float in alcohol. Ice has a density of about 0.92 g/cm³, which is less than liquid water's density (about 1.0 g/cm³), which is why ice floats in water. However, common alcohols like ethanol have a density of roughly 0.79 g/cm³ — lower than ice's density. Since ice is denser than alcohol, it sinks rather than floats when placed in alcohol. This is a classic density-comparison trivia point used to test understanding that floating depends on the relative densities of the solid and the liquid, not just on the object's own properties. "False" is the correct answer.
