The salt in the water does this.
Consider a glass of water filled up to a line on the glass. Then add 3 teaspoons of salt to that glass of water and stir until the salt dissolves. You will find that despite the addition of the salt the water still only comes up to the line.
What has happened is that the salt has gone into solution in the water and the mass of the salt is now part of (inside) the water - the density of the solution has increased.
Sodium makes salt water denser.
the salt water is denser because of the salt
salt water is denser
Salt water is denser than fresh water.
Because salt water is denser. If you pour salt water and fresh water [one with food coloring] into a glass, the salt water will sink below the fresh water. You are only a bit denser than salt water.
Adding salt to water makes the water denser. As the salt dissolves in the water, it adds mass (more weight to the water). This makes the water denser and thus allows more objects to float on the surface that would sink in fresh Water
Seawater because it contains salt which makes the water more dense than water which does not contain salt.
Salt water is denser than fresh.
Salt water has a higher salinity level compared to fresh water, which makes it denser and allows objects to float more easily. Fresh water has a lower freezing point than salt water, allowing it to freeze at a higher temperature.
Salt water is denser than fresh (not salt) water.
Objects float higher in salt water compared to fresh water because salt water is denser than fresh water. The higher density of salt water provides more buoyant force, causing objects to float higher. Additionally, salt water can also affect the rate at which objects sink or float due to changes in the water's viscosity and surface tension.
Salt water is denser than fresh water. Thus, it is easier to float in salt water.
