8.p.8.4 Physical Properties of Matter

Front

What is electrical conductivity?

Back

Electrical conductivity is the ability of a material to allow the flow of electric current. Materials that conduct electricity well, like metals, have high electrical conductivity.

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 is thermal conductivity?

Back

Thermal conductivity is the ability of a material to conduct heat. Materials with high thermal conductivity, like metals, transfer heat quickly.

Front

What are the three states of matter?

Back

The three states of matter are solid, liquid, and gas. Each state has distinct properties and behaviors.

Front

Why is the state of matter considered a physical property?

Back

The state of matter is considered a physical property because it can change (e.g., solid to liquid) without altering the chemical composition of the substance.

Front

What happens to the density of a substance when it is cut into smaller pieces?

Back

The density of each piece remains the same as that of the original substance, as density is a property of the material itself.

Front

What is density?

Back

Density is the mass of a substance divided by its volume. It is a measure of how much matter is packed into a given space.

Front

What is malleability?

Back

Malleability is the ability of a material to be deformed or shaped under pressure, often by hammering or rolling.

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 chemical identity.
