Question

1. If you swim beneath the surface in salt water, will the pressure be greater
than in fresh water at the same depth? Give a reason for your answer​

Answer 1

Yes because density of salt water is greater than freshwater and pressure is given by,
P=h*rho*g+Po
where rho is the density and pressure increases with density

Answer 2

Yes,if someone swims beneath the surface in salt water then the pressure will be greater than in the fresh water.

Because,

• The salt water has greater amount of physical density than the normal fresh water.

• And,the pressure applied by a liquid and the density of that liquid are related in the following way :

Pressure = Density × Depth × Gravitational acceleration

• Now, according to the question,the depth in equal in both situations.

• And,the gravitational acceleration is constant.

• So,the value of density will become the reason behind the less or more value of the applied pressure because rest of the values are constant.

• Now,we came to know that salt water has greater density,so the salt water will apply more pressure than the fresh water.
