Macroscopic properties are qualities that can be seen by the naked eye, and some are relative to the conditions under which a material or element is observed. The three most basic examples of macroscopic properties are color, shape and size.
Other examples of macroscopic properties include texture, phase (solid, liquid or gas), viscosity (if any) and density relative to surroundings (such as oil on water). The properties of an element or material tend to change, even if only slightly, as the conditions change. Examples of changing conditions include how metals tend to glow red when heated to extreme temperatures, how the viscosity of honey decreases with temperature or how the volume of H2O increases slightly when it freezes.
