What happens to water pressure if salt is added?
Salt water has a higher density, so the pressure at a given depth increases.
The boiling point (temperature) rises as salt (a solute) is added, as this interferes with the phase change from liquid to gas - it reduces the average vapor pressure of the salted water, while the atmospheric vapor pressure remains generally the same. In any case, the water evaporates and leaves the salt behind.
The added salt (or any solute) raises the boiling temperature of the water, the temperature at which the vapor pressure of the water is equal to the vapor pressure of the air above it, when molecules will freely transition from the liquid (water) to the gaseous phase (water vapor). The addition of the salt reduces the ability of water molecules to leave the liquid phase (i.e. impedes the transition), raising the effective boiling point temperature…
Currents and thermal gradients aside, salt water is slightly more dense than fresh water, so (at the same depth, for the same temperature) the pressure in salt water will be creater than for fresh water. The difference in pressure will be (pressure in fresh water) x (density of salt water/density of fresh).
no. water without salt evaporates faster because the salt hold down air pressure which takes time to evaporate faster. But it is also due to the tempter of a boiling point of the water. but water without salt has less air pressure because there is no salt no put more air pressure to it. so water without salt evaporates faster than water with salt.
