Why Ice Floats on Water Instead of Sinking

Unusual Solid: Most solids sink in their liquids, but ice is a rare exception.
Molecular Lock: Water molecules form a crystal structure when frozen.
Extra Space: This crystal pattern spreads molecules farther apart than in liquid water.
Lower Density: More space between molecules makes ice less dense than liquid water.
Density Rule: Objects float when they’re less dense than the liquid beneath them.
Floating Proof: An ice cube displaces water equal to its weight, letting it float.
Life Saver: Floating ice insulates lakes and oceans, protecting life underneath in winter.
Climate Link: Icebergs float because the same principle works on a massive scale.
Energy Balance: Freezing releases heat, but the open structure stays light and airy.
Everyday Reminder: Your soda stays cold longer because ice sits on top, melting slowly.
