Question

Give the reason why is it easier to swim in seawater than in freshwater.

Answer 1

1. The seawater is saline as it contains salt.
2. Due to this, the density of seawater becomes more than freshwater.
3. According to the principle of floatation, an object floats on a liquid if its density is less than the liquid.
4. So, it gets easier for a person to swim in seawater than freshwater as the density of the person is less than the seawater.
