Temperature, pressure, and common ion effect
The density of salt water is higher than fresh water.
We know that the density of the sea water is more than the density of the river water. So, the weight of displaced sea water is more than the weight of displaced river water. This weight gives the upward Buoyant force to the swimmer. Thus, the apparent weight of the swimmer is less in the sea water. Hence he finds it easier to swim in the sea water.
Salt increases the density of water, thus makes it easier to float.I've always had troubles floating while swimming in fresh water, but the difference when swimming in the sea is quite noticeable.There are many notes of people doing experiments with floating eggs with salt water versus fresh water.
It depends entirely on the amount of salt in the water. Pure water has a density of 1 kg/L. Any item that is less dense than 1 kgL, will float. Items with a greater density will sink. As you increase the salinity of water, the density of the salt adds to the water's density. The Dead Sea, for example, has a high saline level (31%) and it's density is 1.24kg/L. An average sized person can easily float in these waters.
because it has a higher concentration of ions and minerals!!! ions and minerals play a vital role to make sea water more dense. secondly, the molecular mass: water: h(2) + o(16) = 18g/mol NaCl = n(23) + cl(35.5) = 58.5g/mol NaCl has a higher moleculer mass so there is higher density than water seen!

Temperature, salinity, and pressure.
Sea water has density because it contains dissolved salts and other minerals, which increase its mass without significantly changing its volume. Additionally, temperature and pressure variations in the ocean can also affect the density of sea water.
Freezing point (more salt the lower the freezing point). Density (more salt, the heavier the water).
The main factors controlling the density of seawater are temperature and salinity. Colder water is denser than warmer water, and water with higher salinity is denser than water with lower salinity. Other factors, such as pressure and the presence of dissolved gases, can also influence seawater density.
the density of sea water increases as salinity increases and temperature decreases
depth and salinity increases density of sea water increases
Sea water and fresh water does not have the same density because sea water has salt, which makes it more dense than fresh water Sea water and fresh water does not have the same density because sea water has salt, which makes it more dense than fresh water
Sea water has salt, and therefore a higher density.
Three factors are evaporation and freezing of sea water.
sea water has a higher density
At sea level, fresh water has a density of 1. 0 grams per milliliter. Seawater has a higher density than fresh water, 1. 025 g/ml.
