Question

Why is floating ice less submerged in the brine than water?

Answer 1

Hint: To answer this question, we must have a concept of density and is defined as the mass per unit volume is called density. And we know that solid has more density and liquid has a relatively low density. So, we can say that which has low density will float and with the high density that will shrink.

Complete answer:
Let’s understand what brine is: Brine, or salt water, is a highly concentrated solution of common salt in water (sodium chloride). Natural brines are commercially important sources of common salt and other salts, such as chlorides and sulphates of magnesium and potassium, and can be found underground, in salt lakes, or in saltwater. And we know that the brine or salty water is denser than that of water so we can easily say that the ice will be less submerged in the brine than water.

And we can also say that in brine the floating ice experiences more upthrust i.e., (The upward force exerted by a fluid against the weight of a partially or totally immersed object is known as buoyancy, or upthrust. The weight of the overlying fluid causes pressure to rise with depth in a column of fluid.) as compared to water.

Note: All this can be easily understood with the help of Archimedes' principle, when an object is submerged in water, the upper and bottom sides of the object have opposing forces. This is owing to the fact that the pressure exerted by the water column at a given depth increases with depth. When the body is immersed in water, Archimedes noticed how the up push generated on the body is related to the water.
