Answer 2

Answer:

Feather and wax will float on water. Feathers take up more space for the same weight and they are less dense.The wax is made from fatty acids an oily substance which are less dense than water hence it floats over water.

Aluminium will sink in water. The density of aluminium is greater than the water it displaces, so it sinks.

Common salt will dissolve in water as dissolved salt adds to the mass of the water and makes the water denser than it would be without salt. Because objects float better on a dense surface, they float better on salt water than fresh water.
