The boiling point of water will increase if gelatin will be added to the water. The reason for this is because gelatin adds to the concentration of the liquid resulting to higher boiling point.
Firstly, we tried to boil water in the kettle and added detergent to see if the detergentwould evaporate in the heat but it didnt. We then added detergent to water and boiled in on the stove but the detergent didn't evaporate as predicited.
No it does not
Boiling-point elevation describes the phenomenon that the boiling point of a liquid (a solvent) will be higher when another compound is added, meaning that a solution has a higher boiling point than a pure solvent. This happens whenever a non-volatile solute, such as a salt, is added to a pure solvent, such as water. The boiling point can be measured accurately using an ebullioscope.
Yes, Salt also lowers the freezing point of water, and lowers the boiling point of water. Add salt to a boiling pot of water and it immediately boils faster/harder at the location that the Salt hit the water.

The boiling point increases, thus the water would stop boiling, unless more energy is suppled than before.
If you have floated a needle on the surface of the water in a glass then adding a little detergent will cause the needle to sink. This is because the presence of the detergent changes the surface tension of the water so that it can no longer support the needle.
because of exothermic reaction b/w water and detergent

Do it, and prepare to pick soap out of your nose.
False. When detergent or soap is added to water then it surface tension decreases.
To ensure smooth boiling
Because the detergent reduces the surface tension of the water.
The needle floats on the tensioned surface of the water. When the detergent is added, the surface tension is broken and the needle sinks. Larva of mosquitoes hang from the surface to breath air. Pond-skaters can move across the surface, as can many aquatic insects. Detergent will also cause insects to sink.
Any added impurity can change the boiling point of a liquid.
Any material added to water raise the boiling point.
