To make it cook faster
yes the salt raises the temperature to boil faster
Since salt is an electrolyte, yes, it does cook faster, but it's not that much of a difference.
Water is a bad conductor of heat.salt has a slightly high boiling point
Raises the temperature at which the water boilsAdding salt does not make the water boil faster, but makes the water boil at a higher temperature than 100 degrees Celsius. This may allow you to cook food in that water faster than in plain boiling water.
It takes to long to get the noodles softened.
Because salt raises the boiling point of water...which is why you cook things like eggs and pasta in salted water: because of this effect, the water gets hotter and the food gets done faster.
There is the opinion that cooking would be faster; I did not notice this effect.
the salt is made of heat so it evaporate faster
Yes, actually the salt makes your water boil at a higher temperature. So instead of your water boiling at 100 degrees Celsius it boils at 110 degrees Celsius. So when you put your noodles in they cook faster. :)
Salt
No. Salt affects the uptake of water to any plant so it cannot make corn grow faster.
