Density

it is the mass of unit volume

• weight

• mass of an object

• density

If an object has a density of 3.6 g/mL and you put it into water, will it sink or float?  

• sink
• float

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.

What is the formula for density?

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

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
