What are physical properties of matter?

Back

Physical properties are characteristics that can be observed or measured without changing the substance's identity, such as color, density, and state.

Front

What is density?

Back

Density is the mass of an object divided by its volume, often expressed in grams per cubic centimeter (g/cm³).

Front

What is an electrical insulator?

Back

An electrical insulator is a material that does not allow electricity to flow through it easily, such as rubber or glass.

Front

What is a mixture?

Back

A mixture is a combination of two or more substances that retain their individual properties and can be separated by physical means.

Front

How can you separate a mixture of gravel, iron filings, and water?

Back

You can use a screen to separate gravel, a magnet to separate iron filings, and a paper filter to separate water.

Front

What happens to sugar when it dissolves in water?

Back

When sugar dissolves in water, it breaks down into smaller particles, but it retains its sweetness.

Front

What does it mean for an object to float?

Back

An object floats if it is less dense than the fluid it is placed in.

Front

What is the order of density for the following items: penny, water, plastic paper clip, oil, cork?

Back

The order from most dense to least dense is: penny, water, plastic paper clip, oil, cork.

Front

What is the role of a magnet in separating mixtures?

Back

A magnet can attract magnetic materials, such as iron filings, allowing them to be separated from non-magnetic materials.
