Density Calculations

Front

What is the formula for calculating density?

Back

Density = Mass / Volume

Front

If an object has a mass of 50g and occupies a volume of 25cm³, what is its density?

Back

2 g/cm³

Front

What is the unit of measurement for density in the metric system?

Back

g/cm³ (grams per cubic centimeter)

Front

How does temperature affect the density of a substance?

Back

Generally, as temperature increases, density decreases due to expansion.

Front

What is the relationship between mass, volume, and density?

Back

Density is the ratio of mass to volume; if mass increases while volume remains constant, density increases.

Front

What is the density of water at 4°C?

Back

1 g/cm³

Front

How can you determine the volume of an irregularly shaped object?

Back

By using the water displacement method.

Front

What is the density of a substance that has a mass of 120g and a volume of 30cm³?

Back

4 g/cm³

Front

What happens to the density of a substance when it is compressed?

Back

The density increases as the volume decreases.

Front

What is the significance of an object's density in terms of buoyancy?

Back

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