Something boils when its vapor pressure equals the atmospheric (barometric) pressure above it. When the two are equal, that defines the boiling point.
Therefore, you can either boil something by heating the liquid, and thus raising its vapor pressure (vapor pressure goes up with temperature), or you can boil something by reducing the atmospheric pressure above it until it matches the vapor pressure.
See the Related Questions links to the left for more information about how the boiling point of water changes with elevation and atmospheric pressure.

∙ 12y agoThe boiling point of a liquid decreases with pressure.
For example, if you went up a mountain and tried to boil a potato (as Darwin did in 1835 I believe) it would not work because the water would boil away before it got hot enough to cook the potato sufficiently.

What is the condensing point for nitrogen?
Liquids don't condense. They are already condensed. Also, condensation and boiling points vary with temperature according to their Pxy-Txy graphs. The "triple point" occurs at the exact temperature and pressure where the vapor, liquid, and solid states of an element all exist at once.If you wanted to figure this out on your own, here's a helpful link with plenty more information for you to read up on: http://tinyurl.com/nodvem
What is the fire point of kerosene?
The precise boiling point will vary, due to the incredibly complex nature of ingredients that go into your average forecourt petrol, but around 95oC at a standard atmospheric pressure of 1 bar. http://www.engineeringtoolbox.com/boiling-points-fluids-gases-d_155.html
Do all substances have their own boiling point and freezing point?
please correct me if im wrong but i think everything that doesnt burn has a melting point Everything has a melting point, no matter how hard or dense. Even diamonds can melt if hot enough. Not everything has a melting point. Some things never change into liquid, they go from solid to gas. Dry Ice does this at room temperature. This process is called sublimation.
Why does water boil at 121 degrees?
Water boils at 121 degrees Celsius under normal atmospheric pressure, which is approximately 1 atmosphere or 101.3 kilopascals (kPa). However, it's important to note that this boiling point is specific to conditions at sea level and can vary based on factors such as altitude and atmospheric pressure.

Can the boiling point of a liquid changes with the amount of the liquid?
The boiling point is a physical property of the liquid that is independent on the liquid amount, It may vary with the pressure on the liquid or vary with due to any additives dissolved in the liquid.
What is the name for the temperature when liquid turns into a gas?
It's called the boiling point. It is the temp where the vapor pressure of the "liquid" is equal to the air pressure around (above) it. This is when the liquid [water] reaches 100 degrees Cecilius [at sea level].
What is the boiling point of any liquids?
Boiling points vary from liquid to liquid.
What is liquid's boiling point?
Boiling point is the temperature in which a substance in a liquid state turns to a gas state. In a pure substance (an element or 1 compound) that temperature is a unique property. For example, pure water boils at 100 degrees Celsius. Methanol has a boiling point of 64.7 degrees Celsius. In pure substances the temperature time graph makes a plateau. The boiling point is the same as the condensation point (where a gas turns into a liquid) for that substance.
What is the temperature at which a substance changes from a liquid state to gas?
The boiling point It is called boiling point, where all the liquid turns into gas at this one temperature (if the substance is pure). However, there are exceptions like water (they can evaporate so it can turn into gas before reaching boiling point of 100 degrees Celsius)
The boiling point of pure water is?
The boiling point of pure water is typically about 100 degrees Celsius. This value can vary based on factors such as pressure. Additionally, impurities in a sample of water can alter its boiling point.
Will the boiling point of water differ different with noon temperature?
Different places have different elevation, and different elevations have different air pressure. It is the ambient air pressure which affects the boiling point of water. Air presses down on water, making it harder for the water to form bubbles. Less pressure produces a lower boiling point. More pressure produces a higher boiling point.
Is boiling point and freezing point matter?
Yes, boiling point and freezing point are physical properties that are specific to matter. The boiling point refers to the temperature at which a substance changes from a liquid to a gas, while the freezing point is the temperature at which a substance changes from a liquid to a solid. These properties vary depending on the chemical composition of the substance.
The temperature at which a given substance will change from a liquid into a gas?
The temperature in which a given substance will change from a liquid to a gas is its boiling point. Every element, compound and mixture has a different boiling point. Use an SI data book or the internet to find the boiling point of a particular suubstance.
What is the specific heat of water when it comes to a boiling point?
The specific heat of water when it comes to a boiling point is 100 degrees Celcius, or 212 degrees Fahrenheit. The boiling temperature can vary based on the vapor pressure of the atmosphere.
What would be the boiling point of water in different countries other than Australia?
The boiling point of water is always ~100oC. However, it will vary depending on impurities (e.g. salt water has lower bp) and pressure (higher pressure, higher bp).
