Question

write any 5 substance which floats on salt water​

Answer 1

Answer:

The answer is just one word-salt. When salt is dissolved in water, as it is in ocean water, that 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.

Answer 2

Answer:

• When you add enough salt, the water can become denser than the grapes. Therefore, grapes can float in the saturated salt water. This also explains why things float more easily in the ocean. The Dead Sea is famous for its extremely high density salt water and people can easily float in it without much effort.

• The egg floats on the salt water because it is supported by the denser salt water. The fresh water is less dense than the salt water and will float on top of the salt water if poured very carefully and slowly.
