What is density?

• The weight of an object
  

• The compactness of atoms in a substance
  

• The volume of a substance
  

• The size of an object
  

What is the formula for calculating density?

• Density = Volume ÷ Mass

• Density = Mass × Volume

• Density = Mass ÷ Volume

• Density = Volume × Weight

Why do objects float or sink?

• They float if their weight is higher than the liquid

• They sink if their density is greater than the liquid

• They sink if they are larger than the liquid

• They float if their mass is higher than the liquid

How does temperature affect density?

• Temperature has no effect on density

• Increasing temperature increases density

• Decreasing temperature increases density

• Increasing temperature decreases density

Why does hot air or water rise?

• Hot air or water is less dense than cooler air or water

• Hot air or water is heavier

• Cooler air or water pushes it down

• Hot air or water shrinks in size

How do atoms move in a solid?

• Atoms move freely but stay close together

• Atoms vibrate in fixed positions

• Atoms move very fast and spread out

• Atoms stay completely still
