You can heat saltwater to make steam which has no salt in it. Then you can collect the fresh water droplets that the steam makes, and it is nice, fresh, drinkable water.
The only reason to heat water to make saltwater is if you wanted to either make the salt dissolve quicker, OR to make a super-saturated solution of salt and water. Heating allows the water to hold more salt than if it were at room temperature, say. When you let that water cool, the salt tends to stay in the water - more salt than room-temperature water should hold. This is called a super-saturated salt solution.

What does 50 grams of salt and 200 mL of water make?
probably a supersaturated solution if you heat it to dissolve all of the salt
What holds heat longer salt water or fresh water?
Salt Water, do to its small salt particles which not only the water holds the heat ,but the salt particles TOO!!! Most brines for heat transfer systems are very heavily salted solutions to the point where there is more salt than water [by weight] in them.
What happens to he salt when you heat?
it's becomes a salt water
