What is density?

Back

Density is the mass of an object divided by its volume, typically 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 is the formula to find the volume of an irregular object using water displacement?

Back

Volume = Final water level - Initial water level.

If an object has a mass of 100 g and a volume of 50 mL, what is its density?

Back

Density = 100 g / 50 mL = 2 g/mL.

Front

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

Back

The density increases.

What is the density of water?

Back

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

Front

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

Back

If the object's density is less than 1 g/mL, it will float; if greater, it will sink.
