Why does salt water boil faster than freshwater?

Answer 1

The salty water will reach a lower boiling point than the tap water because when you add salt into water in diffuses and makes the waters boiling point lower because the properties of the water have changed.

salt water will boil just a couple of second faster than tap water, but its just an old wives tale that you can speed up the boiling points of water by 5 mins, etc.

Answer 2

.........because it just does make it appear to boil faster by causing disolved gases (air) to be immediately released by the salt taking up the space of the disolved gases and "kicking" the disolved gases out. "bubbles (air)" form and rise and we "fools" think we see "boiling (water vapor not air)". Salt water ALWAYS takes longer (higher temperature) to produce bubbles of vapor (boil); no matter what substance you stick in it.

Answer 3

Fresh water boils faster than salt water. This is because salt increases the boiling temperature and lowers the freezing temperature of water. Both fresh water and salt water will reach 100 degrees Celsius (212 Fahrenheit) at roughly the same rate, but salt water will only boil at a higher temperature (depending on the concentration of salt). Another factor that affects the boiling and freezing points of water is altitude. The higher you are - the lower the boiling point and the higher the freezing point.

Answer 4

Because salt adds on density and the more water is solidfied the more it absorbs heat. because salt adds density and the more water is solified the more it can absorb heat.

Answer 5

No it boils slower because the salt won't evaporate.

Answer 6

When adding salt to water it will boil faster. This occurs because the presence of salt in the water increased the boiling point.

Answer 7

Salt lowers the boiling point of the water, which make the water reach its boiling point at a lower temperature, resulting in a faster boil.

Answer 8

I don't know why.... good question
