OK, I know that salt water boıls at a higher temperature than fresh water, so therefore fresh water boils quicker. What I want to know is, do they both increase in temperature at the same rate? If given the same heat and conditions, do they both increase in temperature at the same rate but then salt water raches its boiling point later? Or does one of them heat up faster before boiling? and why? why are the solutes changing the properties of the water? thanks

Salt water will actually have a higher boiling rate, in theory. Adding salt makes the liquid(water) a solute. Salt water conducts electricity better than fresh water.This is because common salt is composed of Sodium Chloride which is an ionic compound and ionic compounds conduct electricity very well as a solute. Concordantly, in theory it should conduct heat quicker also, making its rate of temperature gain, bigger.

Salt water has a higher capacity for holding heat than fresh water does, simply because the dissolved salts in it also hold heat.

I think that saltwater heats faster than fresh water.. only because it conducts electricity more easier (higher in alkaline) than fresh water.
Now the solutes in the water i don't think would change the state of the water, its still a liquid, but i believe that it would be more dense (the saltwater) than fresh water.

No. Fresh water heats faster.
