how could i rise boiling point of water?

Although adding salt to water will raise the boiling point, you will need to add a lot of salt.  If this is water that will be used for cooking anything, it will ruin it.  For example, to raise the boiling temperature 1/2 degree celsius, requires 1/4 Cup of Salt!\n\nWhen a pot is boiling over, just turn down the heat or remove it from heat.  You could add some salt, which will change the vapor pressure and slow down the boiling process, but it takes a lot.

A liquid boils when its vapor pressure equals the pressure above the liquid.  At a given temperature, the vapor pressure of a liquid is constant.  At higher altitudes, the atmospheric pressure (the pressure above the liquid) is less than it is at lower altitudes, so water will boil at a lower temperature.

You can't make water boil by compressing it directly.  If you compress it, but allow the hest caused by compressing to leave, then you'll get nothing.  It is possible if you have an insulated system to compress it in such a way that temperature of the water rises, but at higher pressures, the temperature needed to boil water increases.  If the water, once heated by comprsession, were to be rapidy brought to a lower pressure through a throttling valve, it could be vaporized.\n\nBut really, if you want water to boil, you should *DECREASE* the pressure.  In out space, water at room temperature would instantly boil due to the low pressure involved.

Add heat.\nAdd a catalyst.

One way is to use the Clausius-Clayperon Equation.  See the link below and use the boiling point of water for one of the pressure and temperature pairs.  \n\nP.S.  It's equation 22 in the linked document.

Get an electrical heating element, a DC power supply, a thermometer, a voltmeter and an ammeter.\nPass electricity through the heating element, dipped into a measured volume of water (or salt water) in an insulated cup, and measure the current, the voltage and the time taken. This will give you the heat energy supplied. Measure the temperature rise, and work out how much energy would be required to raise 1g of water (or salt water) by 1 degree Celcius. The answer should be close to 4.2!

It mainly depends on the pressure (if we are talking about pure water). The higher the pressure, the higher the boiling point - it can be much lower (ex. high in the mountains) or much higher than 100 degrees C (the boiling point under normal atmospheric pressure). If we don't talk about pure water, then adding other chemicals (for example, table salt - sodium chloride) can raise the boiling point as well.

Boiling is vapour pressure phenomenon. A liquid always exerts a pressure in the space just above it due to evaporation of its surface molecule which is called vapor pressure of that particular liquid and as temperature is raised the vapour pressure goes on increasing. When vapor pressure of the liquid exceeds atmospheric pressure liquid starts to boil.\nin case of a mixture, the solute molecules bind the molecules of the solvent and thus there are fewer surface molecule available to evaporate from the liquid surface. Due to which vapour pressure exerted by a mixture is always less than vapor pressure of pure solvent. To make vapor pressure of mixture to reach the atmospheric pressure level its temperature should be raised more than temperature of solvent alone. Thats why a mixutre has a boiling point elevation.

No. Hot water will boil quicker because it is closer to water's boiling point. At sea level the bp of water is 100 C. (The boiling point is a little less at higher elevations). Once it gets heated to that it doesn't get hotter but rather it changes to a vapor. Cold water requires more energy over a longer period of time to heat it to the required temperature to reach its boiling point.

the boiling point of water at sea level is 212 deg F. the boiling point of water in the mountains is different because the column of air is not as "tall" as it is at sea level. the boling point is when the vapor pressure of a heated liquid exceeds the atmospheric pressure. sea level has a certain atmospheric pressure and thus a certain boiling point for water. at high altitudes the pressure is less and below sea level the pressure is greater.

Hmmm.. The one affecting the boiling point is the intermolecular force..\nAs you can see, most of the compound here is polar. \n\nTherefore all you have to do is if the compound is consisted only of 2 elements (Group 17), you'll have to calculate the electronegativity difference. The more difference between them, the boiling will increase as well.\n\nIf there is more than 2 atoms in a molecule, you'll have to see the dipole moment magnitude (a.k.a polarity). The higher the magnitude, the higher the boiling point will be.\n\n\npeace\nvixklen

Water boils at 212 F.  The hotter the water, the less energy is needed to achieve this temp.  Of course pressure counts too.  Higher altitudes require different amounts of energy.  I think this is Doyles law.  Chem 101 would be a good class to learn this type of thing.  Also the purity of the water makes a difference.  The less pure the water (minreals, other impurities with lessen the amount of energy needed to achieve boiling temp.

Are you seriously a 4th grader...^\n\nProbably because the liquid may be slightly impure and the only way to get the true boiling point of the liquid is to measure the temperature at the reflux ring.

heat it up.  The higher the heat, the faster the reaction.

You can\n1.) Boil the solution and reduce the solution, increasing saturation\n2.) Add more solute\n3.) reduce the temperature of the solution so it has a lower point of saturation.
