• mL/g

Which units of measurement are used for volume?

• g

• cm

• g/mL

• mL

What is the formula for density?

• density = mass x volume
• density = mass / volume
• density = mass + volume
• density = mass - volume

Which of the following is not a characteristic of matter?

• Matter is made up of extremely small particles

• There is no space between particles of matter

• The particles of matter are continuously moving

• The particles of matter attract each other.

At higher temperatures

Object A and B have the same mass but different shape. When put on a beam balance, what will happen?

• Object B will tilt down.

• It will stay balanced.

• Object A will tilt down.

What two types of measurements make up DENSITY? 

• Mass and Volume
• Temperature and Mass
• Grams and Centimeters
• Volume and Weight

Look at this image.  Which object has the LOWEST density in water? How? 

• The Ping Pong Ball because it floats to the top 
• The bolt because it has sunk to the bottom
• The soda cap because it is not just full of air like the Ping Pong ball
