Water has a high boiling point because its molecules are bound together by hydrogen bonding, which is a very strong intermolecular force. It takes more kinetic energy, or a higher temperature, to break the hydrogen bonding between water molecules, thus allowing them to escape as steam.
The boiling point of water is 100 degrees Celsius or 212 degrees Fahrenheit at one atmosphere of pressure or at sea level. However, at high altitudes, like on a mountain, water boils at a lower temperature. When atmospheric pressure increases, water boils at a higher temperature.
According to the chemistry department of Elmhurst College, water boils because it has reached the temperature at which its molecules are moving fast enough for the water's vapor pressure to equal or exceed the atmosphere's vapor pressure. Vapor pressure can be defined as the degree that liquid molec
Water boils when the thermal energy in the water, which is a type of kinetic energy which causes the water molecules to move around, exceeds the strength of the hydrogen bonds between the molecules, causing them to separate from the other molecules. This breaking of bonds between water molecules con
The fastest way to boil water is to fill a pot with hot tap water, cover the pot and place it on the stove on the highest heat setting. Pure water boils faster than water with salt or other impurities.
It takes five to 10 minutes to boil 6 to 8 cups of water. The water, pot and stove temperatures; the water's salinity; the pot's volume, surface area and conductivity; the altitude; and whether or not a lid is in place affect the amount of time needed to boil water.
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.
The boiling point of pure water is 212 degrees Fahrenheit at one atmosphere of pressure, or 760 millimeters of mercury. Such conditions are known as standard pressure. The boiling point is affected, however, when the pressure rises or falls, according to the Department of Chemistry at Purdue Univers
When salt is added to water, it raises the boiling point, requiring the salt water to reach a higher temperature to boil. The boiling point increases as more salt is added to the water.
The boiling point for pure water is 212 degrees Fahrenheit and the melting point is 32 degrees. Pressure and the purity of the water can have an impact on the melting and boiling point.
