Density

Front

What is density?

Back

Density is a measure of how much mass is contained in a given volume. It is calculated using the formula: Density = Mass/Volume.

Front

What are the units used to measure density?

Back

The common units for density are grams per cubic centimeter (g/cm³) or grams per milliliter (g/mL).

Front

How do you calculate the density of an object?

Back

To calculate density, divide the mass of the object by its volume: Density = Mass (g) / Volume (cm³ or mL).

Front

If an object has a mass of 10g and a volume of 2cm³, what is its density?

Back

Density = 10g / 2cm³ = 5 g/cm³.

Front

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

Back

An object with a density greater than water (1 g/cm³) will sink.

Front

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

Back

An object with a density less than water (1 g/cm³) will float.

Front

What is the density of a rock that has a mass of 14g and a volume of 2cm³?

Back

Density = 14g / 2cm³ = 7 g/cm³.

Front

Why does a ping pong ball float in water?

Back

A ping pong ball floats in water because its density is less than that of water.

Front

What is the relationship between density and buoyancy?

Back

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

Front

If an object has a density of 3.6 g/mL, will it sink or float in water?

Back

It will sink because its density is greater than that of water.
