Density Practice

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 unit of density for solids?

Back

The unit of density for solids is typically grams per cubic centimeter (g/cm³).

Front

What is the unit of density for liquids?

Back

The unit of density for liquids is typically grams per milliliter (g/mL).

Front

If an object has a mass of 50g and a volume of 25cm³, what is its density?

Back

Density = Mass / Volume = 50g / 25cm³ = 2.0 g/cm³.

Front

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

Back

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

Front

How does temperature affect the density of a substance?

Back

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

Front

What is the density of water at 4°C?

Back

The density of water at 4°C is approximately 1.0 g/cm³.

Front

How can you determine if an object will float or sink in water?

Back

An object will float if its density is less than that of water (1.0 g/cm³) and sink if its density is greater.

Front

What is the formula to find the volume of an irregularly shaped object using water displacement?

Back

Volume = Final water level - Initial water level.
