Yes, water density will affect an object's ability to float.
The water density is higher than the boat's therefore it floats on the water.
The density is important; for floating an object must have a density under the water density (1 g/cm3).
Oil density of water is lower.
No that is to do with density differences not size differences,
The salt water has a greater density and the floating is easier.
Mass affects the density of a object which therefore affects the floating and sinking of it
the density
ice floating on top of water because water has more density than ice.
Salt increases the density of water, thus makes it easier to float.I've always had troubles floating while swimming in fresh water, but the difference when swimming in the sea is quite noticeable.There are many notes of people doing experiments with floating eggs with salt water versus fresh water.
An object will float if it has less density than the fluid in which it is placed; if the object has more density, it will sink.
Salt in the water
the density of the cork is lower than the density of the water- so it floats.
