Density Review

Front

What is density?

Back

Density is the mass of an object divided by its volume, typically expressed in units like kg/m³ or g/cm³.

Front

How do you calculate density?

Back

Density = Mass / Volume.

Front

What is the density of water?

Back

The density of water is approximately 1 g/cm³ or 1000 kg/m³.

Front

What happens to an object with a density greater than water when placed in water?

Back

It will sink.

Front

What happens to an object with a density less than water when placed in water?

Back

It will float.

Front

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

Back

Density = 50g / 25ml = 2 g/ml.

Front

Does adding more of the same liquid to a container change its density?

Back

No, the density of a liquid remains the same regardless of the amount.

Front

What is the density of Mercury?

Back

The density of Mercury is 13.55 g/cm³.

Front

If a substance has a mass of 90g and a volume of 30ml, what is its density?

Back

Density = 90g / 30ml = 3 g/ml.

Front

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

Back

Density is a measure of how much mass is contained in a given volume.
