which boils faster water or saltwater?

Answer 1

salt water
because as the water is heating the salt particles colide and more heat is given
so salt water

Answer 2

The boiling point is the temperature at which the vapor pressure equals the atmospheric pressure of the surroundings. The explanation you are looking for is called boiling-point elevation. Adding salt to water raises the boiling point. Therefore, water will boil at 100 degrees and saltwater will boil at a higher temperature. Water without salt boils faster.

Answer 3

The answer is sea water for the reasons stated below.

If you look at how fast water boils when you add a small amount of salt to it, such as when cooking your noodles, the change is insignificant between pure water and the salted water. However, if you take two identical pots and add one gallon of pure water to one pot and one gallon of 20 percent salt water to the other and heat the two pots on identical stoves, the pot containing the salt water will come to a boil first.

The time it takes a bucket of liquid to boil is controlled by essentially three things. The first is how much heat or energy you put into the bucket. The second is how fast the temperature rises in response to the heat input (the liquid's heat capacity), and the third is the boiling point of the liquid. Assuming that we can control our stoves and add the same amount of energy to each pot, this variable becomes insignificant.

The boiling point of water does rise if you add salt to it, but only by about 2°C (4°F) to 102°C (216°F). Remember, water boils at 100°C (212°F). This is an insignificant change for adding such a large amount of salt. For you science nerds out there, the boiling point increase is calculated using the "ebullioscopic" constant of water. This leads us to the important variable, how fast water or salt water heats up, or the solution's heat capacity.

The heat capacity of water is very high. What this means is that it takes a lot of energy to raise the temperature of water 1°C; in fact, the calorie is defined as the amount of energy that it takes to heat one gram of water to 1°C.

Now back to the question. If you look at the heat capacity of salt water, you will find that it is less than pure water. In other words, it takes less energy to raise the temperature of the salt water 1°C than pure water. This means that the salt water heats up faster and eventually gets to its boiling point first.

Why does salt water have a lower heat capacity? If you look at 100 grams of pure water, it contains 100 grams of water, but 100 grams of 20 percent salt water only contains 80 grams of water. The other 20 grams is the dissolved salt. The heat capacity of dissolved salt is almost zero when compared to the high heat capacity of water. This means that the heat capacity of a 20-percent salt solution is 80 percent that of pure water. Twenty percent salt water will heat up almost 25 percent faster than pure water and will win the speed race to the boiling point.

Answer 4

Ordinarry water boils faster than sea water.
It is becauseof a phenomenon known as Elvation in boiling point that when a solute is added to a solvent Boiling point of pure solvent increases increases
Here solvent is water in sea water there are several solutes which increase the boiling point
boiling point of sea water is 100.6 degree celcius where as pure water is 100 degree celcius

So that is my answer.

Answer 6

Water boils faster. Contaminants lower the freezing point of water (which is why we put salt on the roads in the winter) and elevate the boiling point.

Answer 7

Salt raises the boiling point of water, so it will take longer to reach the boiling point.

Answer 8

plain water will boil faster.

Saltwater takes longer due to having to break down the Salt first - more isotops.

Answer 9

when any othe substance is added to water, its boiling point increases ...........so salt water will have high boiling point than pure water ......so pure water will boil faster!

Answer 10

fresh water
