Density

Front

What is density?

Back

Density is the mass of an object divided by its volume, usually 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 objects with a density less than water?

Back

Objects with a density less than water (1 g/cm³) will float.

Front

What happens to objects with a density greater than water?

Back

Objects with a density greater than water (1 g/cm³) will sink.

Front

If an object has a mass of 10g and a volume of 5cm³, what is its density?

Back

Density = 10g / 5cm³ = 2 g/cm³.

Front

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 compared to the fluid's density.

Front

Why do helium balloons rise?

Back

Helium balloons rise because helium is less dense than the surrounding air.

Front

True or False: The density of a specific material can change with temperature and pressure.

Back

True. Density can change with temperature and pressure.

Front

What is the density of water?

Back

The density of water is approximately 1 g/cm³.
