Which property describes how well a material lets heat pass through it?

Thermal conductivity. Metals conduct heat well; insulators like wood do not.
Which property tells whether a material dissolves in water?

Solubility. Soluble materials dissolve; insoluble don't.
What property describes a material's ability to float or sink in water?

Density compared with water. Objects less dense than water float; denser objects sink.
Identify the property tested by placing a sample in water to see if it dissolves.

Solubility. Sugar dissolves; plastic does not.
Which property describes whether a material can float or sink in water?

Which property best distinguishes a sponge from a plastic block when both are the same size: absorbency or hardness?

Absorbency. Sponges soak up water while plastic blocks repel it.
Identify the property tested by checking whether a paper clip sticks to a bar magnet.

Magnetism. Iron objects stick to magnets; copper does not.
What is the definition of density as a property used to distinguish materials?

Mass per unit volume. Calculated by dividing mass by volume to identify materials.
What is a chemical property of a material?

A characteristic describing how a material can change into new substances. Involves reactions that create new substances.
Which property describes how much mass is in a given volume of a material?

Density. Calculated as mass divided by volume.
Which property best distinguishes salt from sand when both look similar: solubility in water or texture?

Solubility in water. Salt dissolves completely in water while sand settles.
Which term means a characteristic you can observe or measure to identify a material?

A physical property. Observable or measurable characteristics help identify materials.
Which property describes the ability of a material to bend without breaking?

Flexibility. Rubber bands bend easily while glass rods break when bent.
Which property describes a material's ability to soak up water into its surface or spaces?

Absorbency. Paper towels absorb water while plastic repels it.
Identify the property tested when you compare how rough or smooth two materials feel.

Texture. Sandpaper feels rough while glass feels smooth to touch.
What is the formula for density using mass and volume?

$D = \frac{m}{V}$ . Density equals mass divided by volume.

Magnetism. Testing if the nail is attracted to the magnet.
Which property describes how much light passes through a material (clear, cloudy, or opaque)?

Transparency. Glass is transparent, wax paper is translucent, wood is opaque.
What property describes a material's resistance to being scratched?

Hardness. Diamond scratches glass; talc is easily scratched.
Which property describes a material's resistance to being scratched?

Hardness. Harder materials scratch softer ones.
What property describes whether a material can be stretched into a wire?

Ductility. Copper can be drawn into wires; glass cannot.
Which property describes how well a material lets electric current pass through it?

Electrical conductivity. Metals conduct electricity; rubber and glass do not.
Which property best distinguishes aluminum foil from plastic wrap when stretched?

Malleability. Aluminum can be hammered flat; plastic tears.
Which property describes whether a material allows water to pass through it?

Permeability. Water flows through cloth but not through plastic sheets.
Which property describes whether a material can be pulled into a wire?

Ductility. Most metals can be stretched into wires.
Identify the property being tested when a solid is placed in water to see if it dissolves.

Solubility. Testing if the solid dissolves in water.
Which property best distinguishes a glass window from a wooden board when light shines through?

Transparency. Glass is transparent; wood is opaque.
Which property describes how easily a material breaks or shatters when force is applied?

Brittleness. Glass and ceramics shatter easily while metals bend first.
What property describes whether a material can be hammered into a thin sheet?

Malleability. Gold can be flattened; brittle materials shatter.
Which property describes a material's ability to let electric current pass through it?

Electrical conductivity. Metals conduct electricity; insulators don't.
Which property describes a material's ability to transfer heat?

Thermal conductivity. Metals transfer heat well; insulators don't.
Which property is most useful to distinguish a steel paper clip from an aluminum one: magnetism or flexibility?

Magnetism. Steel is magnetic while aluminum is not magnetic.
Which property describes whether a material is attracted to a magnet?

Magnetism. Materials are either magnetic or non-magnetic.
What property describes whether a material can be bent without breaking?

Flexibility. Rubber bands bend; glass shatters when bent.
Which property describes how easily heat moves through a material?

Thermal conductivity. Metals conduct heat well while materials like wood are insulators.
Identify the property being tested when two objects are compared to see which scratches the other.

Hardness. The harder object scratches the softer one.
Identify the property tested by rubbing two materials to see which scratches the other.

Hardness. The harder material scratches the softer one.
Which property best distinguishes wax from metal if both are solid: melting point or color?

Melting point. Wax melts at low temperature while metal needs high heat.
What property is being tested when you check if a material dissolves in water?

Solubility. Salt dissolves in water; sand does not.
Which property describes whether a material can be hammered into a thin sheet?

Malleability. Most metals can be flattened without breaking.
Which property describes the temperature at which a solid becomes a liquid?

Melting point. Each material has a specific melting temperature.
Which property describes whether light can pass through a material clearly, partly, or not at all?

Transparency (transparent, translucent, or opaque). Light passes through, partially, or not at all.
Which property describes whether a material can be bent without breaking?

Flexibility. Flexible materials bend; brittle ones break.
Which material property best distinguishes copper wire from a rubber band in a circuit?
