Density

Front

What is density?

Back

Density is the mass of an object divided by its volume. It is usually expressed in grams per milliliter (g/mL) or kilograms per cubic meter (kg/m³).

Front

How do you calculate density?

Back

Density = Mass / Volume

Front

What is the unit of density?

Back

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

Front

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

Back

The density increases.

Front

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

Back

The density decreases.

Front

If an object has a density less than 1 g/mL, will it float or sink in water?

Back

It will float.

Front

If an object has a density greater than 1 g/mL, will it float or sink in water?

Back

It will sink.

Front

What is water's density at room temperature?

Back

Water's density at room temperature is approximately 1 g/mL.

Front

What is the principle of displacement?

Back

The principle of displacement states that when an object is submerged in a fluid, it displaces a volume of fluid equal to the volume of the object.

Front

How do you find the volume of an irregularly shaped object?

Back

You can find the volume of an irregularly shaped object by measuring the amount of water it displaces when submerged.
