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 two measurements are needed to calculate density?

Back

Mass and Volume.

Front

If a liquid is less dense than water, what will happen when it is poured into water?

Back

It will float on top of the water.

Front

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

Back

The density increases.

Front

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

Back

The density decreases.

Front

Which liquid is denser: oil or syrup?

Back

Syrup is denser than oil.

Front

What is the relationship between density and layering of liquids?

Back

Liquids with different densities will form layers, with the denser liquid at the bottom and the less dense liquid on top.

Front

How can you determine which of two objects is denser?

Back

You can compare their masses and volumes; the object with more mass for the same volume is denser.

Front

What is the unit of measurement for density in the metric system?

Back

Grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).

Front

Why do some objects float while others sink in water?

Back

Objects float if they are less dense than water and sink if they are more dense than water.
