Archimedes principle
Ice is less dense than water so it floats in water . But the densities of ice and water are close , so most of an iceberg is submerged , even in salt water which is denser than pure water .a) For the specific gravities of ice and water given in the table on the next page what fraction of the volume of the ice cube in a glass of pure water will be above the surface ? If you used salt water of specific gravity from the same table what fraction of volume of the ice cube would be above the surface ?
b)If the cube’s volume is (1.0 cm)^3 What is the weight of the cube ?
c) What is the weight of the part of the cube above water level in pure water ?
d) What is the weight of the part below water level in pure water ?
e) What is the weight of the pure water displaced by the sunken part of the cube ? How does this compare with your answer to part (b) ? Does this make sense ?
