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.

Put the liquids in order from most dense to least dense?

• 4, 3, 2, 1
• 1, 2, 3, 4
• 3, 4, 2, 1, 
• 4, 3, 1, 2

Frank has an eraser. It has a mass of 4g, and a volume of 2cm³. What is its density?

• 8 g/cm³

An irregularly shaped piece of gold was lowered into a graduated cylinder holding a volume of water equal to 17 ml. The height of the water rose to 20 ml. If the mass of the gold was 27 g, what was its density?

• 9 g/mL
• 10.5 g/mL
• 6.5 g/mL
• 8 g/mL

An irregularly shaped rock was lowered into a graduated cylinder holding a volume of water equal to 50 ml. The height of the water rose to 75 ml. If the mass of the stone was 250 g, what was its density?

• 15 g/mL
• 5 g/mL
• 10 g/mL
• 20 g/mL
