Density

Front

What is density?

Back

Density is a measure of mass per unit volume, typically expressed in grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).

Front

What happens to density if mass increases while volume remains constant?

Back

If mass increases while volume remains constant, density increases.

Front

What happens to density if volume increases while mass remains constant?

Back

If volume increases while mass remains constant, density decreases.

If an object has a density greater than that of water, what will happen when it is placed in water?

Back

If an object has a density greater than that of water (1 g/cm³), it will sink.

If an object has a density less than that of water, what will happen when it is placed in water?

Back

If an object has a density less than that of water (1 g/cm³), it will float.

What is the relationship between density and buoyancy?

Back

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

What is the unit of density in the metric system?

Back

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

How does temperature affect the density of liquids?

Back

Generally, as temperature increases, the density of liquids decreases because the liquid expands.
