Do Objects Float Better in Saltwater or Freshwater?

Objects are more buoyant in saltwater than they are in freshwater because saltwater weighs more than freshwater. The saltwater exerts a greater upward force on the object than freshwater, allowing it to float more easily.

The ability of objects to float better in saltwater can be attributed to the Archimedes Principle, which states that the upward force on a submerged object is equal to the weight of the water it displaces. Displacing a cubic foot of freshwater results in an upward force of 62.4 pounds, while displacing a cubic foot of saltwater results in an upward force of 64.1 pounds.
