It is because of the higher ______ of sea water that it is easier to swim in the sea.
A
Viscosity
B
Density
C
Surface tension
D
Buoyancy
Correct Option:
B

Sea water contains dissolved salts and is therefore denser than fresh water. According to Archimedes’ principle, a denser liquid produces a greater buoyant force for the same displaced volume, so a swimmer floats more easily.
