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.

Adding one mole of salt raises the boiling point of the water more than adding one mole of sugar to the water
No, because you can't boil sugar. It will decompose beforehand. However, you can distinguish sugar and salt by heating them. Sugar will melt and decompose before 300 Celsius. Salt will not melt until ~800 Celsius
Na+ ions and Cl- ions are formed from salt ... twice as many particles are dissolved as the sugar. So the boiling point will be higher for the salt solution.
The boiling point of oxygen is -182,962 0C. The boiling point of sodium chloride is 1 413 0C.
The boiling point decrease from lithium to caesium.
I've never heard of a law for this, it is just a property that has been well documented. There are table to give the exact boiling point at almost any pressure.
Table salt and table sugar are both white and grainy. They both dissolve in water and other liquids.
Table sugar or sucrose melts at about 186°C (367°F).
The melting point is a physical property.
Salt and sugar are generally known as crystals but if you increase the temperature enough (1413 degrees for table salt) they will pass the boiling point and enter the gaseous phase where they become gasses (or strictly speaking a plasma)
both solids perhaps
