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 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

What is the density of water?

Back

The density of water is 1 g/cm³.

Front

If an object has a density greater than 1 g/cm³, will it sink or float in water?

Back

It will sink.

Front

If an object has a density less than 1 g/cm³, will it sink or float in water?

Back

It will float.

Front

What is the principle of buoyancy?

Back

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

Front

What is the relationship between temperature and density?

Back

Generally, as temperature increases, density decreases because substances expand.

Front

What is a density column?

Back

A density column is a layered arrangement of liquids with different densities, where denser liquids sink to the bottom.
