100°C or 212° F
The boiling point of water also depends on the purity of the water. Water which contains impurities (such as salted water) boils at a higher temperature than pure water. This phenomenon is called boiling point elevation, which is one of the colligative properties of matter. Here's the answer to this common question. Answer: Short Answer: The boiling point of water is 100°C or 212° F at 1 atmosphere of pressure (sea level). At normal atmospheric pressure, i.e. near sea level, water boils at 212 F or 100 C. The fact that it is tap water, not pure water, would make very little difference. 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 prope … rties of the water have changed. Distilled (pure) water should boil at 100 degrees C at standard pressure (ie not at the top of Everest!) Tap water will boil at a higher temperature due to impurities / added minerals. Perkins · 9 years ago. Thumbs up.  Hard Water: Hard water defines water with a high level of dissolved mineral salts. Therefore, hard water boils at a higher temperature. The difference in the boiling point between typical supplies of hard and soft water is about a degree or two. Alcohol: Alcohol has a lower boiling point that water (about 175&deg F as compared with 212&deg F).  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 boiling point of distilled water seems to be 100 degrees celcius, based on the previous web sites I have seen. Tap water has more minerals, so it has a higher boiling poin … t- 101 degrees Celsius. Salt water does not have a specific boiling point because the temp. is based on how mush salt there is. more salt=higher temp. I hope this helped because I am doing a paper on this and I have to know my stuff! 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. 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. Vapour pressure of water is depend on temperature. At 100 oC, vapour pressure of water will be at the same as atmospheric press … ure so it boil. Salt, is in solid state and virtually had no vapour pressure. Presence of salt mean the vapour pressure is diluted. 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 prope … rties of the water have changed. The boiling point of water is 100°C or 212° F at 1 atmosphere of pressure (sea level), but water boils at a lower temperature as you gain altitude (e.g., on a mountain) and boils at a higher temperature if you increase atmospheric pressure (lived below sea level). Here's the answer to this common question. Answer: Short Answer: The boiling point of water is 100°C or 212° F at 1 atmosphere of pressure ( The boiling point of tap water varies slightly based on factors such as atmospheric pressure and the amount of dissolved solutes in the water. However, it is generally a … round 100oC at standard atmospheric pressure. 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 prope … rties of the water have changed.
