you measure the water before boiling. after boiling would be more tricky.
all the elements that has low boiling point than of the water.
Adding an impurity to boiling water, such as salt, sugar, or other substances, can change the boiling point of the water. The impurity will raise the boiling point of the water, meaning it will need to reach a higher temperature to boil. This effect is known as boiling point elevation.
Adding dissolved CaCl2 to water increases the boiling point of the water. Calcium chloride dissociates into ions in the water, which disrupts the ability of water molecules to escape into the vapor phase during boiling, raising the boiling point.

The salt would dissolve, which you can reverse by boiling the water.
Obviously not.
The higher the pressure being exerted on the water, the lower the boiling point becomes. Yes the boiling point is affected in a pressurized system. If you put water in a sealed container and kept raising the pressure it will eventually reach it's boiling point without the need of adding heat.
Which is most likely be the temperature of boiling water? 100oC is the boiling point of pure water - when water is boiling, it stays at a constant temperature until all of it is evaporated.
Eventually the boiling water would be completely evaporated, leaving a dry pot. An aluminium pot would have the bottom burnt out.
They would die.
The boiling point of water become 102 oC.
