Which is heavier: water or ice?

An ice berg floats on fresh water with a part of it outside the water surface. Calculate the fraction of the volume of the ice berg which is below the water surface. (Density of ice = 917 "kgm"^(-3) , Density of water = 1000 "kgm"^(-3) )

Gold is 19 times heavier than water. Copper is 9 times heavier than water. In which ratio gold and copper should be mixed so that mixture is 15 times heavier than water ?

Write the indicators and causes for the other changes given below. Change of ice into water and water into ice

H_(2)O is a covalent molecule and the two O-H bonds are of polar nature. The H_(2)O molecules are involved in intermolecular hydrogen bonding both in water and ice which differ in their relative densities. (i) What type of structure does ice possess ? (ii) Out of ice and water, which is heavier ? (iii) At what temperature,does water have maximum density ? (iv) What is the value associated with this characteristic of water ?

Give the name of phenomenon in which ice converts to water due to applied pressure and re-converts to ice after removal of pressure.

The temperature at which ice changes to water under normal conditions is -
