Properties of Matter Waygrounds Practice

What are physical properties?

• Physical properties are characteristics that can be observed or measured without changing the identity of the substance.

• Physical properties are characteristics that can only be observed during a chemical reaction.

• Physical properties are the abilities of a substance to conduct electricity only.

• Physical properties are the changes that result in the formation of a new substance.

Answer explanation

The correct choice defines physical properties as observable or measurable characteristics that do not alter the substance's identity, distinguishing them from chemical properties, which involve changes in composition.

Which of the following is an intrinsic property?

• Mass

• Volume

• Density

• Amount of substance

Answer explanation

Density is an intrinsic property because it depends only on the material itself, not on the amount or shape. In contrast, mass, volume, and amount of substance are extrinsic properties that can change with quantity.

Which of the following is an extrinsic property?

• Boiling point

• Melting point

• Mass

• Density

Answer explanation

Mass is an extrinsic property because it depends on the amount of substance present, while boiling point, melting point, and density are intrinsic properties that do not change with the quantity of the material.

Fill in the blank: Density is calculated using the formula Density = ____ / Volume.

• Mass

• Weight

• Length

• Area

Answer explanation

Density is defined as mass per unit volume. Therefore, the correct term to fill in the blank is 'Mass', as it directly relates to the calculation of density.

What is the formula for the volume of a solid object?

• Volume = (length)(width)(height)

• Volume = (length) + (width) + (height)

• Volume = (length) × (width) ÷ (height)

• Volume = (length) - (width) + (height)

Answer explanation

The correct formula for the volume of a solid object is Volume = (length)(width)(height). This formula calculates the space occupied by the object by multiplying its three dimensions.

What is the typical unit for measuring mass?

• Grams or kilograms

• Liters

• Meters

• Seconds

Answer explanation

The typical unit for measuring mass is grams or kilograms, as these are standard units in the metric system. Liters measure volume, meters measure length, and seconds measure time, making them incorrect choices.

What is the ability of a material to conduct heat called?

• Thermal conductivity

• Electrical resistance

• Magnetic permeability

• Optical density

Answer explanation

The ability of a material to conduct heat is known as thermal conductivity. It measures how well heat is transferred through a material, making it the correct choice among the options provided.

What does high thermal conductivity mean?

• High thermal conductivity means heat passes through easily (e.g., metals).

• High thermal conductivity means heat cannot pass through at all.

• High thermal conductivity means the material is a good insulator.

• High thermal conductivity means the material melts easily.

Answer explanation

High thermal conductivity indicates that a material allows heat to flow through it easily, which is characteristic of metals. This means they are efficient at conducting heat.

What property of matter is being illustrated in the diagram?

• Density

• Solubility

• Conductivity

• Malleability

Answer explanation

The diagram illustrates density, which is the mass of a substance per unit volume. It shows how different materials can have varying densities, affecting their buoyancy and behavior in fluids.

Fill in the blank: ________ is the ability of a material to conduct electricity. Metals are typically good conductors, while insulators (like rubber) are not.

• Electrical Conductivity

• Thermal Expansion

• Magnetic Permeability

• Elasticity

Answer explanation

Electrical Conductivity is the ability of a material to conduct electricity. Metals are good conductors due to their free electrons, while insulators like rubber do not allow electricity to flow easily.
