Boiling point A liquid at high pressure has a higher boiling point than when that liquid is at atmospheric pressure. For a given pressure, different liquids boil at different temperatures. For example, water boils at 100 °C (212 °F) at sea level, but at 93.4 °C (200.1 °F) at 2,000 metres (6,600 ft) altitude.

Why does increasing the pressure of water raise the boiling point? At a pressure of 0.5atm, water boils at 85°C...and, at about 0.15atm, the boiling point of water is around 55°C. When water at a higher pressure and temperature and at its boiling point is decompressed to 1.0atm, the expansion causes instantaneous conversion to steam and the temperature drops to 100°C.eport Abuse. The boiling point of water at atmospheric pressure (1.0atm) is 100°C. This due to the Vapour Pressure of water at 100°C is 1.0atm. If the pressure on the water is increased, the molecules leaving the liquid have to build up a pressure equal to the pressure acting upon the water.

- Boiling point of water is inversely proportional to atmospheric pressure, which depends on altitude and weather. Higher altitude, lower boiling point. Water boils at 100 C …at sea level. Go below sea level (ocean level) to the Dead Sea and the boiling point will actually be greater than 100 C.

- A: The boiling point of salt water depends on the percentage of salt. Water with 20 percent salt boils at 216 degrees Fahrenheit, as opposed to 212 degrees Fahrenheit for pure water. Adding a small amount of salt to a pot of boiling water does not make it boil significantly faster.

- Answer: The boiling point of water at sea level is 100oC (212oF). Water boils when the pressure of the vapor is equal to the surrounding pressure. Since atmospheric pressure is reduced at higher altitudes it takes less energy (and therefore less heat) to boil water.

The Boiling Point of Water Conventionally, the water temperature at which water boils is considered to be 100 degrees Celsius or 212 degress Fahrenheit. However, these numbers are only valid at sea level. As barometric pressure changes so too does the boiling point of water. For instance, as elevation increases the boiling point lowers. On the top of Mount Everest, for example, boiling water is possible at a water temperature of 68 degrees Celsius or 154 degrees Fahrenheit. Conversely, in deep ocean vents, water can be much hotter than that without boiling.

What is the freezing point of water, melting point of ice, boiling point of water? Here's the answer to this common question. Answer: The boiling point of water is 100 C or 212 F at 1 atmosphere of pressure (sea level). However, the value is not a constant. The boiling point of water depends on the atmospheric pressure, which changes according to elevation.

What is the boiling point of water? At higher altitudes, the pressure is lower, and so water boils at a lower temperature. If the barometric pressure is not at the standard value, the boiling point will be different. For example, water boils at 72 degrees Celsius on Mount Everest.

Does distilled water boil at the same temperature that regular tap water does? 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.

How fast does water cool off after boiling? As long as you are talking about a normal pot with or without a normal lid (i.e. not a pressure cooker) and you are reasonably close to sea level, you're right, boiling water is at 100°C. However, if you start to climb in altitude, that is no longer the case, at 300m, water boils at 99°C, at 600m, 98°C and so on. Wikipedia has a page with information about High altitude cooking that contains a reference table.

What Temperature Does Water Boil At? Boiling Point & Elevation From the highest land point above sea level, Mount Everest, to the lowest, the Dead Sea, water’s boiling point can vary from just below 70 ˚C to over 101 ˚C. The reason for this variation comes down to the differences in atmospheric pressure at different elevations.

What are the Safest Temperature Settings for a Hot Water Heater? Some pediatricians instead suggest setting the hot water temperature at 120° F (48.88° C). With this water temperature, a child would have to run water over the same place for ten minutes prior to receiving a severe burn. Temperatures higher than 125° F can burn a child, or an adult quite severely, and quite quickly.
