Density

Front

What is Density?

Back

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

Front

How do you calculate Density?

Back

Density = Mass / Volume.

Front

What units are used for Density?

Back

Common units for density include grams per cubic centimeter (g/cm³) and kilograms per cubic meter (kg/m³).

Front

What is Mass?

Back

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

Front

What is Volume?

Back

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

Front

What happens to Density when you heat a substance?

Back

Generally, when a substance is heated, it expands, which can decrease its density if the mass remains constant.

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.

Front

What is a common example of a substance with low density?

Back

Helium is a common example of a substance with low density, which is why helium balloons float.

Front

What is a common example of a substance with high density?

Back

Lead is a common example of a substance with high density.

Front

How does temperature affect the density of liquids?

Back

In general, as the temperature of a liquid increases, its density decreases.
