It's not! Pure water has a density of 1.000 g/ml. Sea water has a density of 1.025 g/ml and saturated salt water has a density of roughly 1.2 g/ml.
Water is pure by nature, however it gets dense due to different impurities. Impurities such as salt and tiny minerals cause the water to get dense.
No, rain water is almost pure water as it has evaporated and will only contain small dust particles from the atmosphere. Salt water contains disolved salt and is therfore more dense.
Cold water is more dense.
salt water is more dense than tap water
Salt water will be more dense than the water, but less dense than the salt.
Salt
on top. Wood is less dense than water to the point that it float on top of water, and salt water is more dense and has a higher surface tension than pure water so the wood would, if possible, float higher.
Yes; that is why objects float more easily in salt water. yes, its true, the dead sea is so dense because of the salt that people can just float on top effortlessly The salt that is added dissolves into the water. The mass of the salt then adds to the mass of the water, increasing the density.
Because of the salt - salt is denser than water.
Salt water in more dense.The higher the salinity, the denser it is.
S-I-N-K .
A fresh egg don't float in pure water; in a salty water the floating depends on the concentration of the salt in solution. The salty water is more dense.
