Mercury is used as a barometric luquid because it is "___________" times denser than water.

An ice cube of side 1 cm is floating at the interface of kerosene and water in a beaker of base area 10 cm^(2) . The level of kerosene is just covering the top surface of the ice cube. a. Find the depth of submergence in the kerosene and that in the water. b. Find the change in the total level of the liquid when the whole ice melts into water.
