Density and Buoyancy Review

Front

What is density?

Back

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

Front

How do you calculate density?

Back

Density = Mass / Volume.

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

What is buoyancy?

Back

Buoyancy is the ability of an object to float in a fluid, determined by the object's density compared to the fluid's density.

Front

If an object has a density of 1 g/mL, what will happen when it is placed in water?

Back

It will neither sink nor float; it will be suspended.

Front

What is the formula for calculating the volume of an irregular object using water displacement?

Back

Volume = Final water level - Initial water level.

Front

If an object displaces 10 mL of water, what is its volume?

Back

The volume of the object is 10 mL.

Front

What is the density of an object that has a mass of 200 g and a volume of 100 mL?

Back

Density = 200 g / 100 mL = 2 g/mL.

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; it will sink if it is more dense.
