There is a general tendency for objects to expand when they get hotter - this includes air, and gases in general. As a result, they have less density (mass per unit volume); and objects with less density tend to float or rise.
Objects that float in water are less dense than water; while objects that sink in water are more dense than water.
Objects always have more buoyancy in denser fluids than less dense fluids. Therefore, swimmers would float more easily in very salty water.FUN FACT:The Dead Sea, in Jordan, Israel, is so salty that you can float on the surface!

A liquid that is less dense than water will float - oil being one example.
yes
Objects float better in salt water. It is more dense, therefore, it is more difficult to move through.

Objects that are less dense than the environment in which they are immersed will float, unless they are tethered.
Buoyancy
it is salty and salty waters are dense
Objects that are less dense than the environment in which they are immersed will float, unless they are tethered.
objects that are less dense float to the top.
Objects always have more buoyancy in denser fluids than less dense fluids. Therefore, swimmers would float more easily in very salty water.FUN FACT:The Dead Sea, in Jordan, Israel, is so salty that you can float on the surface!
Any object that is less dense than water will float.
The more salt there is in water the more buoyant an object is. The salt makes the water dense. Objects only float if they have less density than salt.
