Ch 08 - A Journey through States of Water6th Science

Properties of the Solid State

Describe the physical properties of water in its solid state (Ice) regarding shape and flow.

CONCEPT

Shape: Fixed. A solid retains its specific shape irrespective of the container it is placed in.
Volume: Fixed.
Flow: Solids do not flow or spread outwards.
Example: An ice cube maintains its rigid cubic shape whether it sits in a cup, a bowl, or on a flat plate.

Solid = Stubborn Shape

Properties of the Liquid State

How does liquid water behave fundamentally regarding shape and volume?

CONCEPT

Shape: Not Fixed. Liquids possess no inherent shape and will naturally contour to take the shape of the container they are poured into.
Volume: Fixed. The physical amount of space the liquid occupies remains constant (e.g., 1 Litre of water remains exactly 1 Litre whether in a tall bottle or a wide bucket).
Flow: Liquids flow and spread easily over surfaces.

Liquid = Lazy Shape, Loyal Volume

Properties of the Gaseous State

What are the unique physical properties of water in its gaseous state (Water Vapour)?

CONCEPT

Shape: Not Fixed.
Volume: Not Fixed. Gases expand dynamically.
Spreading: Gases naturally spread out in all directions to fill the entire available space of any container or room.
Visibility Note: Pure water vapour is a completely invisible gas. (The white 'steam' we often see is actually condensed liquid droplets, not gas).
