Yes, salt water boils at a higher temperature than distilled water. It also boils more slowly.

Yes, because of a phenomenon we call Boiling Point Elevation. Boiling point is the temperature at which the vapor pressure is equal to the atmospheric pressure. Since adding salt will increase the intermolecular forces of attraction, the tendency of water escaping liquid phase as water vapor will decrease. This is because of the decrease in the vapor pressure of the water. So it will need a higher temperature at which the vapor pressure will be equal to the atmospheric pressure and then it will boil.

Yes
By Raoult's Law & the 4 Colligative Properties of dilute solutions, such as salt water. By adding a solute to a solution:
1) The vapor pressure of the solution relative to the solvent is lowered
2) The elevation of the boiling point of the solution
3) The depression of the freezing point
4) The phenomenon of osmotic pressure
---- looking at 2) in particular
By adding a solute to a solution it lowers the vapor pressure of the solution. BOILING is defined as when the vapor pressure of the solution is equal to that of the atmospheric pressure, or the standard 1 atm.
Therefore...
YES, it adding salt (a solute) to a water (solvent) causes the the vapor pressure of solution to go down and the boiling point to go UP!

Adding salt to water will cause the water to boil at a higher temperature. Also, the salty water will "boil" slower than regular water.

Yes, it boils at a slightly higher temperature and freezes at a lower temperature than pure water.

Yes,it increases the boiling point of water.

It sure does...salt water boils at a higher temp and slower to freeze.

Yes, salt solution conducts heat quicker than just plain water.

It makes it boil faster, not sure if it changes the temp though. The second you put salt in pretty hot water, it begins to slightly boil, fun to watch.

Yes, it raises the boiling point.
