IB Physics Melting Icebergs

A tutorial set of questions on floating objects is given below.

  1. An ice cube floats partially submerged in a container of water. Does the water level rise when the ice melts? See Physics Education 36, no 1, p75 Jan 2001 .

  2. An iceberg floating in the sea melts. Does this cause the sea level to rise?

  3. A steel ball bearing floats in a beaker of mercury. Water is now poured on top of the mercury. Does the ball bearing sink, rise or stay the same depth in the mercury?
