Yes. Not by more than a few degrees Centigrade, though. It's a matter of adding particles to the water. The type of particles is largely irrelevant, but the particles must be heated as well, increasing the boiling point, depending on the amount of particles added.
Adding salt to water the boiling point increase.
This is a colligative property.
Yes; the boiling point is the same for table salt and table sugar. The boiling point of the water will increase by the same amount based on the number of particles of solute in the solution.
At the boiling point salt become a gas.
Yes, but only sightly. It takes a large amount of salt to even increase the boiling point by 4° F (2° C).
Dissolved ions in solution will increase the boiling point of the liquid. Salt in cooking water does this.
Yes, most nonvolatile solutes such as sugar or glycerin will increase water's boiling point.
Add impurities (salt and others) to the substance.
It doesn't. It's just an old wives tale
The boiling point is higher.
it increases the boiling point
if you increase the pressure, the boiling point (temperature) will also increase.
