Density Review # 2

Front

What is density?

Back

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

Front

How do you calculate the volume of an irregular object?

Back

The volume of an irregular object can be calculated using water displacement. Subtract the initial water level from the final water level after the object is submerged.

Front

What is the formula for density?

Back

Density = Mass / Volume.

Front

What happens to the density of an object if its mass increases but its volume remains the same?

Back

The density of the object increases.

Front

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

Back

Mass is directly proportional to density and volume is inversely proportional to density.

Front

If two objects have the same mass but different volumes, which one has a higher density?

Back

The object with the smaller volume has a higher density.

Front

What is the density of water?

Back

The density of water is approximately 1 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 g/cm³) and sink if its density is greater.

Front

What is the significance of water displacement in measuring volume?

Back

Water displacement allows for the measurement of the volume of irregularly shaped objects by observing the change in water level.

Front

If an object has a mass of 100 g and a volume of 50 cm³, what is its density?

Back

Density = Mass / Volume = 100 g / 50 cm³ = 2 g/cm³.
