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 (D) = Mass (m) / Volume (V).

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 of the object increases.

Front

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

Back

The density of the object decreases.

Front

What is the relationship between density and buoyancy?

Back

An object will float in a fluid if its density is less than the density of the fluid; it will sink if its density is greater.

Front

How does temperature affect the density of liquids?

Back

Generally, as temperature increases, the density of liquids decreases.

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

If an object has a density of 0.8 g/cm³, will it float or sink in water?

Back

It will float, as its density is less than that of water.

Front

What is the formula for the volume of a cube?

Back

Volume (V) = side length (s)³.
