Density Flashcard

Front

Why do some substances float on water?

Back

They are less dense than water.

Front

True or False: The density of a specific type of material never changes.

Back

True.

Front

I have two objects with the same volume but different masses. Which object will be more dense?

Back

The object with more mass.

Front

What is the formula for density?

Back

Density = mass / volume.

Front

Put the liquids in order from most dense to least dense: 4, 3, 2, 1.

Back

4, 3, 2, 1.

Front

What is density?

Back

Density is the mass of an object divided by its volume.

Front

How does temperature affect the density of a substance?

Back

Generally, as temperature increases, density decreases.

Front

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

Back

The density increases.

Front

What is the unit of density in the metric system?

Back

Kilograms per cubic meter (kg/m³) or grams per cubic centimeter (g/cm³).

Front

If an object has a density of 2 g/cm³, will it float in water?

Back

No, it will sink because it is denser than water (1 g/cm³).
