Question

We know that water's density is 1000 kg / m³and sea water's density is 1025 kg / m³. So, is it easy to swim in water or in sea water?

Solution

when a person is floating on the water the its apparent weight is equal to,
= true weight of the person( Mg ) - weight of the liquid displaced( VÏg )
M is the mass of the person.
Ï is density of the water.
So, if the density water is more then the apparent weight of the person is less. therefore it easy to swim in the see water.
