A loaded cargo ship sails from sea water to river water. State and explain your observation.
Answer
The ship begins to submerge more as it sails from sea water to river water.
The water of a river is of low density than that of a sea. Therefore, when a loaded cargo ship sails from sea water to river water, it sinks further. The reason is that according to the law of floatation, to balance the weight of ship, a greater volume of water is required to be displaced in water of lower density in river.
