Examples of Physical Properties A physical property is any characteristic of a material that can be observed or measured without changing the composition of the substances in the material. Examples: Viscosity, Conductivity, Malleability, Ductile, Brittleness, Hardness, Melting Point, Boiling Point, Density, Size, Shape, and Color

Viscosity Viscosity is a substance’s resistance to flowing. The slower the liquid, the higher the viscosity. The faster the liquid, the lower the viscosity. Viscosity decreases when the substance is heated and increases when the substance cools down. Examples: Maple Syrup- high viscosity vinegar- low viscosity

Conductivity A material’s ability to allow heat or electricity to flow is called conductivity. Materials that have high conductivity are called conductors. (metals)

Malleability and Ductile Malleability is the ability of a solid to be flattened into a thin sheet. (copper, gold, aluminum) Ductile is the ability of a solid to be formed into a wire. (copper)

Others Hardness: How hard or soft is the substance Melting Point: Temp. at which the substance melts. Boiling Point: Temp. at which the substance boils Density: The ratio of mass of a substance to its volume.

Recognizing Physical Changes A physical change occurs when some of the properties of a material change, BUT the substance in the material remains the same. Crumpling a piece of paper Cutting a tomato Physical changes can be reversed Ice, water, and water vapor
