Question

It is easier to swim in seawater than in river water.

• A. True
• B. False

Answer 1

The correct option is A True

1. We know that upthrust from water is required for swimming and the density of the fluid matters in order to gain that upthrust.
2. The upward force acting on an object immersed in a liquid is called upthrust.
3. The denser the fluid, the more the upthrust and this is why it is easier to swim in seawater than in river water.
4. Seawater is denser because salt is dissolved in it.
   Hence, the given statement is True
