* Density: Saltwater is denser than freshwater. This is because the dissolved salt adds mass to the water without significantly changing its volume.
* Buoyancy and Density: The principle of buoyancy states that an object immersed in a fluid experiences an upward force equal to the weight of the fluid it displaces. Denser fluids exert a stronger buoyant force.
* Result: Since saltwater is denser, an object will displace more weight of saltwater than freshwater, leading to a greater buoyant force and making it easier to float.
Example: You might notice that it's easier to float in the ocean than in a freshwater lake. This is because the denser saltwater provides more buoyancy.
