density

Rebus puzzle challenge each day at beginning of class.

SUNKEN ICE CUBES Fill one beaker with plain water. One beaker with alcohol. will look essentially identical. Place an ice cube in each beaker. The ice will float in the water because its density (»0.9 g/cm3) is less than the density of water (»1 g/cm3). The ice will sink in the alcohol because the density of the ice is more than the density of alcohol (»0.8 g/cm3).
