Properties of Matter Practice

Front

What is a physical property of matter?

Back

A physical property is a characteristic of a substance that can be observed or measured without changing the substance's chemical identity. Examples include color, density, and conductivity.

What is a chemical property of matter?

Back

A chemical property is a characteristic that can only be observed during a chemical reaction, indicating how a substance interacts with other substances. Examples include reactivity with acids, combustibility, and oxidation states.

Front

What is conductivity in terms of physical properties?

Back

Conductivity refers to the ability of a material to conduct heat or electricity. It is a physical property that can be measured without altering the material's chemical structure.

Front

What is luster in relation to physical properties?

Back

Luster is the way a surface reflects light, indicating its shininess or dullness. It is a physical property used to describe the appearance of materials.

Front

What is an example of a chemical property?

Back

An example of a chemical property is combustibility, which is the ability of a substance to catch fire and burn.

Front

What does it mean if a substance reacts with bleach?

Back

If a substance reacts with bleach, it indicates a chemical property, as the reaction involves a change in the chemical composition of the substance.

Front

What is the significance of reactivity in chemical properties?

Back

Reactivity refers to how readily a substance undergoes a chemical reaction with other substances. It is crucial for understanding how substances interact in chemical processes.

Front

What is the chemical property of water when it reacts with pure sodium?

Back

When water reacts with pure sodium, it produces hydrogen gas and sodium hydroxide, demonstrating its chemical property of reactivity.

Front

How can you differentiate between physical and chemical properties?

Back

Physical properties can be observed without changing the substance's identity, while chemical properties can only be observed during a chemical change.

Front

What is an example of a physical property that can be measured?

Back

An example of a measurable physical property is density, which is the mass of a substance divided by its volume.
