* Density is key: Buoyancy depends on the density of the liquid. Denser liquids exert a stronger upward force on objects submerged in them.
* Saltwater is denser: When you add salt to water, the salt dissolves and increases the water's density. This is because the salt molecules take up space between the water molecules, making the solution heavier for its volume.
* More buoyancy: Since saltwater is denser than freshwater, it exerts a greater upward force on objects. This means that objects are more likely to float in saltwater than in freshwater.
Think of it like this: It's easier to float in a swimming pool filled with very salty water than in a fresh water pool. You're more likely to bob up and down because the saltwater is pushing you upwards with more force.
