Simply, the greater the amount of salf dissolved in a body of water ('salinity') the greater its upward buoyancy force (more buoyant). The Dead Sea has very high salinity (it is more dense) meaning people who go swimming in it find they are able to float on the surface without effort.
Salt actually increases buoyancy.
Adding salt to water increases the density of the water, which in turn increases the buoyant force acting on objects placed in the water. This increased buoyant force can make objects more buoyant and help them float more easily.
salt. added by new author: As the amount of salt in the water iw increased the freezing point of water is decreased i.e. lowered. This is a negative correlation.
In short. Select an object that would just sink in water. Then using identical sized containers pour an equal amount of water into each, say 3/4 full. Then in each dissolve an increasing amount of salt, from no salt in the first, to large amounts of salt in the last. Then place the same object into each container, starting with the "no added salt" water to demonstrate it would sink in this. Then into the increasing concentrations of salt. If it is suspended in the salt solution and not the first "no added salt" water, you're proven salt water helps objects float
Adding salt in water changes the buoyancy of plain water because the salt makes the water denser. This shows when an egg is place in water with salt, it floats, while with plain water, the egg sinks.
the teeth are made up of certain minerals and when there is a deficiency i.e less amount of that mineral salt is there the teeth are affected
it is easier to float, salt water has a higher density. The more salt, the easier it is to float.
No, Epsom salt does not increase the temperature of boiling water. However, it can help to increase buoyancy and reduce the cooking time of certain vegetables when added to boiling water.
both....and it depends what you are looking to measure if you are looking to measure buoyancy by comparing the two salts then this is the way to do it.
If you add an equal amount of salt to the beaker on the left, the water level in that beaker will rise slightly due to the displacement caused by the added salt. In contrast, the water level in the beaker on the right, which has no added salt, will remain unchanged. The overall increase in water level in the left beaker is a result of the combined volume of the water and the salt.
If you are trying to measure how fast an ice cube melts with or without salt added, your Independent variable would be amount of salt added, and your Dependent variable would be the amount of time it takes to melt.
