Density 1-7 Review

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

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

Back

5 g/cm³

Front

What unit is density commonly measured in?

Back

Density is commonly measured in 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 the relationship between mass, volume, and density?

Back

Density is directly proportional to mass and inversely proportional to volume. If mass increases while volume remains constant, density increases.

Front

Which box has a higher density if Box A has a mass of 20 grams and a volume of 5 cm³, and Box B has a mass of 15 grams and a volume of 3 cm³?

Back

Box A has a density of 4 g/cm³ and Box B has a density of 5 g/cm³. Therefore, Box B has a higher density.

Front

What does it mean if an object is more compact?

Back

If an object is more compact, it means that it has more mass in a given volume, resulting in a higher density.

Front

If the mass of an unknown substance is 5.3 grams and the volume is 2 cm³, what is its density?

Back

2.65 g/cm³ (rounded to 2.7 g/cm³).

Front

What is the volume of a box that measures 3 cm x 2 cm x 5 cm?

Back

30 cm³.
