Density

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) or kilograms per cubic meter (kg/m³).

Front

How do you calculate the density of an object?

Back

Density = Mass / Volume.

Front

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

Back

Volume of the object = Final water level - Initial water level.

Front

If an object has a mass of 30 g and a volume of 10 cm³, what is its density?

Back

Density = 30 g / 10 cm³ = 3 g/cm³.

Front

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

Back

The water level rises by an amount equal to the volume of the submerged object.

Front

What is the density of water?

Back

The density of water is approximately 1 g/cm³ at 4°C.

Front

If an object is less dense than water, what will happen when it is placed in water?

Back

The object will float.

Front

If an object is more dense than water, what will happen when it is placed in water?

Back

The object will sink.

Front

What is the density of a substance with a mass of 100 g and a volume of 50 cm³?

Back

Density = 100 g / 50 cm³ = 2 g/cm³.

Front

How can you determine the mass of a substance if you know its volume and density?

Back

Mass = Density x Volume.
