Units 1 and 2 Earth Science practice

What is the definition of density?

• Relationship between something’s mass and volume

• Property of all matter

• How much “stuff” (matter) in a certain amount of “space” (volume

• All of the above

What are the units for density?

• grams/milliliter

• g/cm3

• g/mL

• All of the above

If an object floats, it is _______ dense than water.

If an object sinks in water, it is ______ dense than water.

The density of water is equal to

• 1.0 g/mL

• 1.0 g/cm3

• Both the choices are correct

How does temperature affect density?

• Warmer things rise and are less dense

• Colder things sink and are more dense

• Warm water rises above cold water

• All of the above

Which gas is more dense than air?

• Hydrogen

• Helium

• Carbon dioxide

The equation for density is

• Density = mass/volume

• Density = volume/mass

• Density x mass = volume

• Mass = volume/density

The density of substance A is 0.98 and the density of substance B is 4.2. Which substance is more dense?

• A

• B
