The density of an ice cube is 0.917 g/cm3. What percentage of the ice cube will float above the surface of antifreeze with a density of 1.11 g/cm3?
here ,
let the volume of the ice cube is V
Now, let the fraction of volume abpve water is x
Now, Using archimedes principle
weight of liquid displaced = weight of ice cube
(1 - x) * V * 1.11 = V * 0.917 * g
solving for x
x = 0.174 = 17.4 %
the percentage of ice cube above water is 17.4 %

The density of ice near 0 C. is 0.917 g/cm3. If a 35 g ice cube floats on the surface of water (1.00 g/cm3), what volume of the ice is visible above the surface?
Water density at 0 C is 0.999 g/cm3, and at 99 C it is 0.958 g/cm3, so why does ice float in hot water if ice is more dense that hot water.
8. Ice has a density of 0.91 g/cm2, so it will float in liquid water. Imagine you have a cube of ice, 10 cm on a side. (a) What is the cube's weight? (b) What volume of liquid water must be displaced in order to support the floating cube? (c) How much of the cube is under the surface of the water?
A cube of copper metal has a density of 8.96 g/cm3. The cube has a mass of 29.54 g. The atomic radius of a copper atom is 1.28 angstroms. How many atoms is the cube of copper metal?
A cube of iron, which has a density of 7.87 g/cm3, has an edge length of 3.75 cm. What is the mass of the sample?
An 13 g ice cube at -18˚C is put into a Thermos flask containing 130 cm3 of water at 18˚C. By how much has the entropy of the cube-water system changed when a final equilibrium state is reached? The specific heat of ice is 2200 J/kg K and that of liquid water is 4187 J/kg K. The heat of fusion of water is 333 × 103 J/kg.
An 15 g ice cube at -23˚C is put into a Thermos flask containing 150 cm3 of water at 17˚C. By how much has the entropy of the cube-water system changed when a final equilibrium state is reached? The specific heat of ice is 2200 J/kg K and that of liquid water is 4187 J/kg K. The heat of fusion of water is 333 × 103 J/kg. Please show explanation and answer.
An ice cube floats in a beaker of ice cold water. Since the water is ice cold, the ice cube is not melting and hence its volume is not changing. The density of water and ice are, respectively, ρw = 1,000 kg/m3 and ρi = 917 kg/m3. (Assume one of the ice cube's faces is parallel to the water's surface.) (a) If the ice cube is 17.0 mm on each side, how far below the surface (in mm) is the...
