physical property
viscosity
conductivity

Explanation:

Physical property

• Definition: A characteristic of a substance that can be observed or measured without changing the substance's chemical identity (e.g., color, density, melting point, boiling point, hardness, etc.).
• Example or something to remember: The color of a copper wire (it's reddish - brown) is a physical property. You can observe the color without changing the copper into another substance. Another example is the density of water, which is $1\ g/cm^3$ at $4^\circ C$. We can measure this density without altering the chemical composition of water.

Viscosity

• Definition: A measure of a fluid's (liquid or gas) resistance to flow. The higher the viscosity, the slower the fluid flows.
• Example or something to remember: Honey has a higher viscosity than water. If you pour honey and water from a spoon, honey flows much more slowly. Another example is motor oil - different grades of motor oil have different viscosities, and thicker (higher viscosity) oils flow more slowly.

Conductivity

• Definition: The ability of a material to allow the flow of heat or electricity. For electrical conductivity, it's the ability to conduct an electric current; for thermal conductivity, it's the ability to conduct heat.
• Example or something to remember: Copper is a good electrical conductor. That's why it's used in electrical wires. For thermal conductivity, metal spoons conduct heat well - if you leave a metal spoon in a hot cup of coffee, the handle will get warm quickly. Wood, on the other hand, is a poor conductor (an insulator) of both heat and electricity.

Answer:

Physical property

• Definition: A characteristic of a substance observable/measurable without changing its chemical identity (e.g., color, density, melting point).
• Example: Color of copper (reddish - brown) or density of water ($1\ g/cm^3$ at $4^\circ C$).

Viscosity

• Definition: A fluid's resistance to flow (higher viscosity = slower flow).
• Example: Honey flows slower than water; thick motor oil.

Conductivity

• Definition: Ability of a material to conduct heat or electricity.
• Example: Copper (electrical conductor, used in wires); metal spoon (thermal conductor, gets warm in hot coffee).
