Density

Front

What is density?

Back

Density is the mass of an object divided by its volume, usually expressed in grams per cubic centimeter (g/cm³) or grams per milliliter (g/mL).

Front

How do you calculate density?

Back

Density = Mass / Volume.

Front

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

Back

They float.

Front

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

Back

They sink.

Front

If an object has a mass of 10g and a volume of 5cm³, what is its density?

Back

2 g/cm³.

Front

Why do some substances float on water?

Back

They are less dense than water.

Front

What is the density of water?

Back

1 g/cm³.

Front

If a brick sinks in water, what can you infer about its density compared to water?

Back

The brick has a higher density than water.

Front

If an object has a density of 0.8 g/mL, will it sink or float in water?

Back

It will float.

Front

What is the relationship between density and buoyancy?

Back

An object will float if it is less dense than the fluid it is in, and sink if it is more dense.
