Unit 3 Review - Density and Matter

What is the formula for density?

• D=m/v
• D=m x v
• D=v/m
• D=m+v

What 2 things do we need to know to find density?

• mass and velocity
• length and width
• mass and volume
• mass and state

How can we tell if an object has less density than water?

• It sinks.
• It floats. 
• It is a liquid.
• It rusts.

Find the density if the mass is 120g and the volume is 40cm³.

• 480g/cm³
• 30g/cm³
• 3g/cm³
• none of the above

The amount of space something takes up

• density
• volume
• mass
• matter

Something that takes up space and has mass.

• volume
• matter
• mass
• density

What do we know about an object's density if it sinks in water?

• The object is less dense than water

• The object is more dense than water

• There is no way to tell what the density of the objects is based on this information.

Mass is a measurement of matter. What common units can we use to measure mass?

• Ounces

• Grams

• Liters

• Pounds

What units do we use to measure the volume of a liquid, like water or Coca-Cola?

• Cubic meters (cm³)

• Grams (g)

• Grams per cubic centimeter (g/cm³)

• Milliliters (mL)

What is the density of water?

• 1.2 grams per milliliter

• 1 gram

• 1 gram per milliliter

• .75 grams per milliliter
