Question
A loaded cargo ship sails from sea water to river water. State and Explain your observations.
Solution
A ship submerges more as it sails from sea water to river water.
Density of river water is less than the density of sea water. Hence, according to the law of floatation, to balance the weight of the ship, a greater volume of water is required to be displaced in river water of lower density.
