Density

Front

What is density?

Back

Density is the amount of matter in a given space.

Front

What causes an object to sink in water?

Back

An object sinks in water if its density is greater than the density of water.

Front

What causes an object to float in a liquid?

Back

An object will float in a liquid if it is less dense than the liquid.

Front

How is density calculated?

Back

Density is calculated by dividing mass by volume (Density = Mass/Volume).

Front

What is the unit of density?

Back

The unit of density is typically grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).

Front

If an object has a density of 1 g/cm³, what will happen if it is placed in water?

Back

It will neither sink nor float; it will remain suspended in the water.

Front

Which is denser: oil or water?

Back

Water is denser than oil.

Front

What happens to the density of an object if its mass increases but its volume remains the same?

Back

The density of the object increases.

Front

What happens to the density of an object if its volume increases but its mass remains the same?

Back

The density of the object decreases.

Front

What is the relationship between density and buoyancy?

Back

Buoyancy is the ability of an object to float, which is determined by its density compared to the fluid it is in.
