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).

Front

How do you calculate density?

Back

Density = Mass / Volume.

Front

What is the unit of density?

Back

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

Front

What happens to the density of an object if its mass increases while its volume remains constant?

Back

The density increases.

Front

What happens to the density of an object if its volume increases while its mass remains constant?

Back

The density decreases.

Front

If an object has a density greater than 1 g/cm³, what will happen when placed in water?

Back

It will sink.

Front

If an object has a density less than 1 g/cm³, what will happen when placed in water?

Back

It will float.

Front

What is buoyancy?

Back

Buoyancy is the ability of an object to float in a fluid, which is determined by the object's density compared to the fluid's density.

Front

What is the principle of flotation?

Back

An object will float if it displaces a volume of fluid equal to its weight.

Front

What is the relationship between density and temperature for most substances?

Back

For most substances, density decreases as temperature increases.
