Question

Why is it difficult to swim under water in the Great Salt Lake?

Short answer

Salty water is denser than regular water, and it is analogous to that of the human body in Great Salt Lake. As a result, going underwater is tough (basically sink in water).

Step-by-step solution

 Step 1: Conceptual Introduction

Fluid statics, often known as hydrostatics, is a branch of fluid mechanics that investigates the state of balance of a floating and submerged body, as well as the pressure in a fluid, or imposed by a fluid, on an immersed body.

Comparing normal water and water in the Great Salt Lake

The Great Salt Lake is a large lake with high salinity. People are able to swim in normal water very easily. Butit became difficult in this lake because of the high amount of salt present in it. Saline water has more density than normal water.

Explaining the high pressure developed inside the lake 

Pressure is directly related to density, depth, and acceleration due to gravity. So, the pressure exerted by the saline water on the body will be large.As pressure increases with height, under the water, it will be greater.So, it is easy to float on the water, but it will be difficult to swim under the water.

Therefore, due to the high density and pressure of the saline water, it is difficult to float under the Great Salt Lake.
