DENSITY DENSITY DENSITY

Front

What is density?

Back

Density is a measure of how much mass is contained in a given volume. It is calculated using the formula: Density = Mass/Volume.

Front

What are the two types of measurements that make up density?

Back

Mass and Volume.

Front

How do you calculate the density of an object?

Back

Density is calculated by dividing the mass of the object by its volume (Density = Mass/Volume).

Front

What is the unit of density in the metric system?

Back

The unit of density is typically grams per cubic centimeter (g/cm³) or grams per milliliter (g/mL).

Front

If an object has a mass of 50 g and a volume of 10 cm³, what is its density?

Back

Density = Mass/Volume = 50 g / 10 cm³ = 5 g/cm³.

Front

Why do helium balloons rise in air?

Back

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

Front

What happens to the density of an object if its mass increases while its volume remains constant?

Back

If the mass increases while the volume remains constant, the density of the object increases.

Front

What is the density of water?

Back

The density of water is approximately 1 g/cm³ at 4°C.

Front

How does temperature affect the density of a substance?

Back

Generally, as temperature increases, the density of a substance decreases because the substance expands.

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.
