Ice Cube and Cork in
Water and Ethyl Alcohol
By comparing the computed densities with the density values found
in standard handbooks, it is possible that liquid A is water while liquid
B is ethyl alcohol (note that other liquids or mixtures may have the
The density of the ice cube (900 kg/m3) is less than the
water's density, but it is greater than the ethyl alcohol's density.
Hence, the ice cube will float on water while it will sink in ethyl alcohol.
On the other hand, a cork of density 250 kg/m3 is less dense
than the water and the ethyl alcohol. Hence, it will float on both the
