Properties of Matter

What is a physical property of matter?

• Taste

• Color

• Density

• Wavelength

Answer explanation

Density is a physical property of matter. It refers to the mass per unit volume and helps identify substances based on their compactness.

What is the density of a material?

• The density of a material is the amount of mass it has in relation to its volume.

• The density of a material is the amount of color it has in relation to its shape.

• The density of a material is the amount of energy it has in relation to its volume.

• The density of a material is the amount of sound it has in relation to its texture.

Answer explanation

The density of a material is the amount of mass it has in relation to its volume. It is a measure of how tightly packed the particles of a substance are. This is the correct choice.

What is the difference between the mass and the weight of an object?

• Mass is the amount of matter in an object, while weight is the speed at which an object falls.

• Mass and weight are interchangeable terms that refer to the same thing.

• Mass is the amount of matter in an object, while weight is the force of gravity acting on the mass.

• Mass is the force of gravity acting on an object, while weight is the amount of matter in an object.

Answer explanation

Mass is the amount of matter in an object, while weight is the force of gravity acting on the mass. This choice correctly explains the difference between mass and weight.

What are the extensive properties of matter?

• They are properties that depend on the temperature of the substance.

• They are properties that depend on the amount of substance present.

• They are properties that depend on the state of the substance.

• They are properties that depend on the color of the substance.

Answer explanation

Extensive properties of matter depend on the amount of substance present.

What is an example of an intensive property of matter?

• Weight

• Volume

• Color

• Density

Answer explanation

Density is an example of an intensive property of matter because it remains constant regardless of the amount of substance.

How can the volume of an irregular object be measured?

• By placing it on a scale and measuring its weight.

• Using a thermometer to measure its temperature.

• Submerging it in water and measuring the displacement of the liquid.

• Cutting it into pieces and measuring each part separately.

Answer explanation

The volume of an irregular object can be measured by submerging it in water and measuring the displacement of the liquid. This method accounts for the irregular shape and provides an accurate measurement.

What is the thermal conductivity of a material?

• Hardness of a material

• Ability to conduct heat

• Weight of a material

• Color of a material

Answer explanation

Thermal conductivity refers to the ability of a material to conduct heat. It is a measure of how well a material can transfer heat energy.

What is the difference between a solid, a liquid, and a gas in terms of shape and volume?

• Solids have a defined shape and volume, liquids have variable shape and volume, and gases have a defined shape and volume.

• Solids do not have a defined shape or volume, liquids have a defined shape and volume, and gases have a variable shape but defined volume.

• Solids have variable shape and volume, liquids have a defined shape but variable volume, and gases have a defined shape and volume.

• Solids have a defined shape and volume, liquids have a variable shape but defined volume, and gases do not have a defined shape or volume.

Answer explanation

Solids have a defined shape and volume, liquids have a variable shape but defined volume, and gases do not have a defined shape or volume.

What is the solubility of a material?

• It is the resistance of a material to electricity

• It is the ability of a material to emit light

• It is the ability of a material to change its physical state

• It is the ability to dissolve in a given solvent.

Answer explanation

Solubility is the ability of a material to dissolve in a given solvent.

How can the density of an object be determined?

• Multiplying the mass by the volume of the object.

• Subtracting the mass from the volume of the object.

• Adding the mass and the volume of the object.

• Dividing the mass by the volume of the object.

Answer explanation

The density of an object can be determined by dividing its mass by its volume.
