7th G_ Density

Front

What is density?

Back

Density is defined as mass per unit volume, typically expressed in grams per cubic centimeter (g/cm³) or grams per milliliter (g/mL).

Front

How do you calculate density?

Back

Density can be calculated using the formula: Density = Mass / Volume.

Front

What is the density of water?

Back

The density of water is 1 g/cm³.

Front

What happens to objects with a density less than water?

Back

Objects with a density less than water will float.

Front

What happens to objects with a density greater than water?

Back

Objects with a density greater than water will sink.

Front

If a rock has a mass of 14g and a volume of 2cm³, what is its density?

Back

The density of the rock is 7 g/cm³.

Front

What is the relationship between mass, volume, and density?

Back

Mass is directly proportional to density and volume; as mass increases, density increases if volume remains constant.

Front

What is an example of a material that floats in water?

Back

Cork is an example of a material that floats in water.

Front

How can you determine the density of an irregularly shaped object?

Back

You can determine the density of an irregularly shaped object by measuring its mass and the volume of water it displaces when submerged.
