Calculating Density

Front

What is the formula for calculating density?

Back

Density = Mass / Volume

Front

If an object has a mass of 10 kg and a volume of 2 m³, what is its density?

Back

5 kg/m³

Front

What units are commonly used to express density in the metric system?

Back

g/cm³ or kg/m³

Front

How does the density of an object affect its buoyancy in water?

Back

Objects with a density less than water (1 g/cm³) will float, while those with a density greater than water will sink.

Front

What is the density of water?

Back

1 g/cm³ or 1000 kg/m³

Front

If a substance has a mass of 50 g and occupies a volume of 100 cm³, what is its density?

Back

0.5 g/cm³

Front

What happens to the density of a substance if its mass increases while its volume remains constant?

Back

The density increases.

Front

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

Back

Density is directly proportional to mass and inversely proportional to volume.

Front

How can you determine if an object will float or sink in a liquid?

Back

Compare the object's density to the density of the liquid.

Front

What is the density of copper if it has a mass of 216 g and a volume of 24 cm³?

Back

9 g/cm³
