Temperature and Density

Why do ice cubes float in a  glass of water?

• the ice cubes are more dense than the water
• the water is more dense than the ice cubes
• the water is more dense than the glass
• the ice is more dense than the glass

Which property of matter is determined by dividing its mass by its volume?

• elasticity
• buoyancy
• density
• viscosity

Mercury is a metal that is liquid at room temperature and has a density of 13.5 g/cm3.  Which of these metals would sink below the mercury if dropped into a container of mercury?

• gold (density=19.3 g/cm3)
• lead (density=11.4 g/cm3)
• iron (density=7.9g/cm3)
• aluminum (density=2.7g/cm3)

A brick sinks in water while a wooden block of the same size floats.  This is because the brick has a

• lower volume than the wooden block
• lower density than the wooden block
• higher volume than the wooden block
• higher density than the wooden block
