Why do objects sink or float in H₂O? 

• Because their densities are higher or lower than compared to water
• Because their densities are using gravity to pull down
• Because their densities are heavier or lighter
• Because their mass and volumes are equal 

Why does ice float?

• Liquid water is less dense than solid water.
• Solid water is less dense than liquid water.
• Gaseous water is less dense than solid water.
• Liquid water is less dense than gaseous water.
