Salt water is salty because of chemicals that are dissolved in the water. The water is still H2O, the same as fresh water.
Fresh water (of the same temperature) has the lower density ('lighter').
this depends on where the water is, if its in a swamp in the everglades it is considered brackish which is both salt and fresh water, in the ocean the water is salt water, if your at a lake, pond, or stream then it is fresh water, and if you are talking about water in a salt water pool the water isnt really salt water it just has chemicals to have the same effect.
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).
At the same temperature fresh water evaporates faster.
the same. the salt isn't evaporated, only the h2o, so fresh and salt water evaporate the same unless there is another liquid in one of the two types of water.
Salt water has a greater density than fresh water. So the same object will foat higher in salt water than in fresh, and some things will foat in salt water that are too dense to float in fresh water.
Salt water contain dissolved sodium chloride; chemical and physical properties are different compared with fresh water.
Fresh and salt water are very different for one key reason, fresh water doesn't contain salt and salt water obviously does. There are different flora and fauna in fresh and salt water for this reason.
yes
on fresh salt water
Salt water is water that has salt in it and it is found in oceans. Fresh water does not have salt and is found in rivers and lakes.
The sun heats both fresh water and salt water through a process called solar radiation. However, salt water has a higher heat capacity and can hold more heat than fresh water. This means that salt water will heat up more slowly than fresh water, but it will also retain heat for a longer period of time. In general, both types of water will eventually reach the same temperature when exposed to the same amount of sunlight.
