Density

Front

What is density?

Back

Density is the measure of how much mass is contained in a given volume. It is calculated by dividing mass by volume.

Front

What is mass?

Back

Mass is the measurement of the amount of matter in an object, usually measured in grams or kilograms.

Front

What is volume?

Back

Volume is the amount of space that an object occupies, typically measured in liters or cubic centimeters.

Front

How do you calculate density?

Back

Density = Mass / Volume.

Front

What happens to the density of most materials when they are heated?

Back

Most materials decrease in density when heated because their volume increases.

Front

What happens to the density of most materials when they are cooled?

Back

Most materials increase in density when cooled because their volume decreases.

Front

What is the relationship between density and buoyancy?

Back

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

Front

What is the unit of measurement for density?

Back

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

Front

Do all objects have the same density?

Back

No, different materials have different densities.

Front

What is the difference between mass and weight?

Back

Mass measures the amount of matter in an object, while weight measures the force of gravity acting on that mass.
