Physical and Chemical Properties Quiz

Physical Properties

• State: Solid, liquid, or gas
• Color: Hue of the substance
• Hardness: Resistance to scratching or indentation
• Malleability: Substance's ability to be hammered or rolled into thin sheets
• Ductility: Ability of a substance to be drawn into wires
• Brittleness: Tendency of a substance to break easily
• Odor: Smell of the substance
• Texture: Feel, appearance, or consistency of the substance
• Lustre: Shininess or dullness of a substance
• Clarity: How clear or opaque a substance is
• Viscosity: Resistance to flow

Chemical Properties

• Corrosiveness: Ability to cause damage by a chemical reaction
• Flammability: Ability to ignite easily
• Reactivity: Ease of changing when contacted with other substances

Evidence of Physical Changes

• Change in state: Solid to liquid, liquid to gas, etc.
• Blending and mixing: Combining substances without creating a new substance.
• Dissolving: One substance dissolving into another
• Cutting: Dividing a substance into smaller pieces.
• Crushing: Reducing the size of a substance.
• Change of size and shape: Alterations in dimensions without creating a new substance. (e.g., breaking a stick)

Evidence of Chemical Changes

• Color change: A shift from one color to another.
• Odor change: A new or different smell appears.
• Heat or light production: Release of heat or light energy
• Gas formation: A gas is made during the chemical reaction. .
• Precipitation formation: Formation of an insoluble solid in a reaction between two solutions
• Change in temperature: Observing whether the reaction releases or absorbs heat

Physical Change

• A change in which no new substance is made.
• Usually reversible.

Chemical Change

• A reaction that makes a new substance.
• Not usually reversible.
