Physical/Chemical Intensive/Extensive

Front

What is an Intensive Property?

Back

An Intensive Property is a property that does not depend on the amount of substance present. Examples include density, color, and boiling point.

Front

What is an Extensive Property?

Back

An Extensive Property is a property that depends on the amount of substance present. Examples include mass, volume, and total energy.

Front

What is a Physical Property?

Back

A Physical Property is a characteristic of a substance that can be observed or measured without changing the substance's identity. Examples include color, melting point, and density.

Front

What is a Chemical Property?

Back

A Chemical Property is a characteristic of a substance that can only be observed during a chemical reaction. Examples include reactivity with acids, flammability, and oxidation states.

Front

What is a Physical Change?

Back

A Physical Change is a change that affects one or more physical properties of a substance without altering its chemical composition. Examples include melting, freezing, and dissolving.

Front

What is a Chemical Change?

Back

A Chemical Change is a change that results in the formation of new chemical substances. Examples include rusting, combustion, and digestion.

Front

What happens to water when it boils?

Back

When water boils, it undergoes a Physical Change from liquid to gas (steam) without changing its chemical composition.

Front

What happens to ice when it melts?

Back

When ice melts, it undergoes a Physical Change from solid to liquid without changing its chemical composition.

Front

What is an example of an Intensive Property related to color?

Back

The blue color of a substance is an example of an Intensive Property, as it does not change regardless of the amount of the substance.

Front

What is an example of an Extensive Property related to mass?

Back

The mass of a substance is an example of an Extensive Property, as it changes with the amount of substance present.
