first of all you need to know the mineral content of both fresh water and sea water lets start with sea water at the atom level there is chlorine 55.3% sodium 30.8% magnesium 3.7% sulfur 2.6% calcium 1.2% potassium 1.1% and then there are trace elements of maganese / lead / gold / iron / iodine. and trace gases of roddium / argon / helium / lithium / nitrogen / oxygen /carbon dioxide / hydrogen. also keep in mind the pollutants that get added by the washoff of all the rivers and under water volcanos. so with that in mind now what is found in fresh water well there is more iron. and sense the cleaner the water (less elements) it would take a less temp. to make the atoms respond less break down to reach its boiling point where as sea water is more complex containing (more elements) thus more atoms to respond. I hope this was some what helpfull to you Brilliantpebble.
Pure water freezes at 0c and boils at 100c. When you add a contaminant, it changes the freezing and boiling point of the liquid.
A good example, anti-freeze in a car. Mixed with pure water, it now boils at a much higher temperature and freezes at a much lower temperature.
Another example, putting salt on the ground to melt snow. The salt doesn't warm up the snow, it just lowers the freezing point.
Sea water has a large solute volume consisting of various dissolved salts. These dissolved salts form ion-dipole bonds with the water molecules, which are very strong and take a lot of energy to break. Fresh water has a very low solute volume with almost no dissolved salts. The water molecules in fresh water form hydrogen bonds (dipole-dipole) bonds, which are not as strong as ion-dipole bonds and need less energy to break.
Because there are impurities-salt, that you need to heat up together with the water.
Because sea water has salt in it.
Because it has to burn the salt aswell
Sea water will boil at higher temp
Beer boil at a higher temperature than tap water because contain many solutes.
Water is distilled by evaporating it, usually by adding heat and bringing it to boil
distilled water and pure water are the same thing.
Depends on how much and what salt, but definitely higher than pure water.
100 degree cel
A liquid boils when the vapor pressure of the liquid is equal to the atmospheric pressure. The presence of salt in the water reduces the vapor pressure of the water at the temperature at which plain or distilled water will boil. Since the temperature of the salt water must be higher to reach the same vapor pressure as the atmosphere, it takes longer to boil.

less than 100oC.
Due to lower atmospheric pressure at altitude, water will boil at lower temperature.
Salty water boils at a higher temperature than pure water does.
When you boil water, the velocity of moving molecules in water gets increased so as the intermolecular energy of water. For that the temperature of hot water is higher then normal or cold water.
The boiling point of water is 100 degrees Celsius or 212 degrees Fahrenheit. However, water boils at a lower temperature at higher altitude. Salt water boils at a higher temperature than pure water.
The salt acts as a catalyst which prevents the water from boiling at the lower temperature.
