Properties of Water- Density definitions Flashcards

A measure of how tightly packed molecules are in a substance, affecting whether it floats or sinks in another substance.

A state of water where molecules are tightly packed, constantly forming and breaking hydrogen bonds, resulting in high density.

A state of water where molecules form a stable lattice structure, expanding and resulting in lower density than liquid water.

Weak attractions between water molecules, crucial for the formation of water's lattice structure in ice.

An organized arrangement of molecules in solid ice, leading to expansion and lower density compared to liquid water.

The process by which a layer of ice prevents heat loss from the liquid water below, crucial for sustaining life in cold conditions.

Periods of extreme cold in Earth's history, where the insulating properties of ice allowed oceans to remain liquid beneath the surface.

The increase in space between molecules in solid ice due to stable hydrogen bonds, resulting in lower density.

The process where water freezes from the surface downwards, forming an insulating ice layer on top.

Variations in temperature over time, which can lead to freezing conditions that challenge the survival of life.
