DENSITY & PERCENT ERROR QUIZ

When a dense object is placed in a graduated cylinder and the water rises, it rises because of

• added volume

• object is floating

• it wants to

• 
• syrup is at the bottom because it is the most dense

• water is in the middle because it is the most dense

• oil is at the top because it is the most dense
