Density

Front

What is density?

Back

Density is a measure of how much mass is contained in a given volume. It is calculated using the formula: density = mass / volume.

Front

What is the formula for calculating density?

Back

density = mass / volume

Front

What is displacement in the context of measuring volume?

Back

Displacement is the method of measuring the volume of an object by observing how much the water level rises when the object is submerged.

Front

If an object has a mass of 10g and a volume of 2cm³, what is its density?

Back

5 g/cm³

What happens to the water level in a graduated cylinder when an object is submerged?

Back

The water level rises, and the amount it rises is equal to the volume of the object submerged.

Front

What is the unit of density in the metric system?

Back

The unit of density is typically grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).

Front

How does temperature affect the density of a substance?

Back

Generally, as temperature increases, the density of a substance decreases because the substance expands.

Front

What is relative density?

Back

Relative density is the ratio of the density of a substance to the density of a reference substance, usually water.

Front

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

Back

7 g/cm³

Front

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

Back

Density is directly proportional to mass and inversely proportional to volume.
