Three classic, everyday examples of matter that exist firmly in a solid state at normal room temperature include iron, wood, and ice. Iron represents a dense metallic solid with a rigid crystal lattice structure and high tensile strength used extensively in construction. Wood is an organic solid composed of rigid cellulose fibers that provide structural support in nature and manufacturing. Ice is the crystalline solid state of water formed when temperatures drop below freezing, maintaining a fixed geometric shape unlike liquid water.
