Properties of Matter (STAAR Released Questions)

Front

What is solubility?

Back

Solubility is the ability of a substance (solute) to dissolve in a solvent, forming a solution. For example, sugar dissolving in water.

Front

What does density measure?

Back

Density measures how much mass is contained in a given volume. It is calculated by dividing mass by volume (Density = Mass/Volume).

Front

What is a conductor?

Back

A conductor is a material that allows electricity or heat to flow through it easily. Examples include metals like copper and aluminum.

Front

What is the difference between a solution and a mixture?

Back

A solution is a homogeneous mixture where one substance is dissolved in another, while a mixture can be heterogeneous and may not have uniform composition.

Front

What is evaporation?

Back

Evaporation is the process by which liquid turns into vapor, usually when heated. For example, water evaporating when heated.

Front

What is magnetism?

Back

Magnetism is a property of materials that allows them to attract or repel other materials. For example, iron is attracted to magnets.

Front

What is the physical state of matter?

Back

The physical state of matter refers to its form, which can be solid, liquid, or gas. Each state has distinct properties.

Front

What is conductivity?

Back

Conductivity is the ability of a material to conduct electricity or heat. Metals are generally good conductors.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What is a physical property?

Back

A physical property is a characteristic of a substance that can be observed or measured without changing its identity, such as color, density, or boiling point.
