What are physical properties of substances?

Back

Physical properties are characteristics that can be measured or observed without changing the substance's identity.

Front

What is density, and how is it calculated?

Back

Density is the mass of a substance per unit volume, calculated as Density = Mass ÷ Volume.

Front

How is thermal conductivity demonstrated?

Back

Thermal conductivity measures a substance's ability to transfer heat; metals like copper are excellent conductors.

Front

Front

Define melting point.

Back

Melting point is the temperature at which a solid turns into a liquid.

Front

Define boiling point.

Back

Boiling point is the temperature at which a liquid turns into a gas.

Front

Are physical properties dependent on the amount of the sample?

Back

No, physical properties like density, conductivity, and boiling point are independent of the sample's amount.

Front

Why is comparing substances by physical properties important?

Back

Comparing substances helps identify and classify materials for specific uses and scientific studies.
