How do you distinguish between a piece of cotton and a piece of bronze?
they have different properties: density: Bronze has a higher density ~7.8 than cotton ~0.9electric conductivity: bronze conducts electricity, cotton does notthermal conductivity: bronze has a relatively high thermal conductivity cotton relatively lowcolor: bronze is reddish metallic, shiny; cotton is matte whitecoefficient of thermal expansion......Almost all properties differ...
Why is water used as a standard for comparison?
Water is often used as a standard for comparison in various contexts because it is a common and well-understood substance with clear properties and behaviors. Its density, specific heat capacity, and other characteristics make it a useful reference point for understanding the properties of other substances or for calibrating instruments. Additionally, water is essential for life and many natural processes, making it a practical and relevant standard for comparison.
What conductor has the best electrical conductivity at room temperature?
Silver has the best electrical conductivity at room temperature among all natural materials. It is commonly used in electrical wiring and components due to its high conductivity.

How do you classify materials into group?
Materials can be classified into groups based on their physical and chemical properties such as structure, composition, and behavior. Common classification methods include sorting based on properties like conductivity, magnetism, elasticity, and density. Other methods involve grouping materials according to their origin, such as natural versus synthetic, or based on their uses and applications.
Is copper a natural resource?
Yes, copper is a natural resource that is found in the earth's crust. It is typically extracted through mining processes and is used in various industries for its conductivity and other properties.
Does a cotton has higher thermal conductivity than silk?
No, cotton has a higher thermal conductivity than silk. Cotton is a natural fiber that conducts heat more effectively than silk, which is a protein-based fiber known for its insulating properties.
What does the natural frequency of a wave depend on?
The natural frequency of a wave depends on the properties of the medium through which the wave is propagating, such as its density and elasticity. It is also influenced by the boundary conditions of the system and any external forces acting on it.
Why is iodine nonmetal?
Iodine is a nonmetal because it lacks metallic properties such as conductivity and malleability. It exists as a diatomic molecule in its natural state and tends to gain electrons when forming chemical bonds, similar to other nonmetals.
What are the properties of natural rubber?
have elastic properties
