Why does lowered air pressure allow water to boil at room temperature?

Less force pushes down on the liquid, making it easier for gas to escape

Remember that water boils when vapor pressure (pressure of vapor pushing upwards) surpasses air pressure. Lower air pressure would mean a lower vapor pressure would still allow the water to boil. Vapor pressure is affected by temperature.

What is the effect of pressure on boiling point of butane?
If nonsalt water is placed in a closed system (for example an automotive cooling system) then for every pound of pressure the system can handle (ex. radiator cap) the boiling point of water (normally being 212f) is raised by 3 degrees. Thus, if said system can handle only 1 pound pressure before the water boils the temperature of the water when it boils should be 215F. Or so I understand.
How does pressure affect boiling point?
The boiling point is that temperature when the SATURATEDvapor pressure of a liquidbecomes equal tothe surrounding pressure.Thus the higher the sorrounding pressure, the higher the boiling point.
The vapor pressure of a sample of boiling water is 380 torr The temperature of the water is?
The temperature of the water is 100 degrees celsius.
What can you do to increase the temperature of boiling water?
Raise the pressure. It all depends on pressure.
According to the phase diagram for water how is the state of water determined?
The axes of any phase diagram have temperature (x-axis) and pressure (y-axis). With a temperature of 273K and a pressure of 101.325 kPa , water is at its freezing point. Now keeping the same temperature (273K) , but reducing the pressure to say , 100 Pa ,water will be a gas. Conversely, at a temperature of 373K and 101,325 kPa water is at its boiling point. However, if you increase the pressure to say 10 MPa, water remains a liquid. If you keep the same temparture 373 K and increase the pressure to 10GPa then water remains a solid. Another way is to randomly select any given point on the phase diagram, say in the Gas phase and read the temperature and pressure.
When does water boil much less than 100?
When the pressure is reduced. Water only boils at 100 degrees Celsius when the air pressure is one atmosphere. So up a mountain, where the air pressure is lowered, water boils at a lower temperature.
How hot is old faithfuls water get?
Between 1983 and 1994, four probes containing temperature and pressure measurement devices and video equipment were lowered into Old Faithful. The probes were lowered as deep as 72 feet (22 m). Temperature measurements of the water at this depth was 244 °F (118 °C), the same as was measured in 1942.
Does solute effect the freezing point of water?
the temperature at which the solution freezes is lowered.
What 3 factors affect the density of sea water?
Temperature, pressure, and common ion effect
What expands most when the temperature is lowered water or helium or iron or wood?
helium as it is gas.
What fact or measurement would allow you to predict how high the pressure of water vapor inside the cup will rise?
the temperature of the water. I'm sure this is for the program Study Island.

How do you raise body temperature lowered by drug reaction?
drink hot water it helps trust me
The vapour pressure of water at 25degrees is 3.14kPa When 0.050 mol of KNO3 is dissolved in 100ml of water at 25 degrees the vapour pressure is lowered by?
Read a text book
What does a bucket thermometer measure?
it is used to measure the temperature of water's surface that is captured inside of a bucket which is lowered into the water until the surface temperature is registered; then taken out of water and read by user.
Can milk freezes faster then water?
milk will always freeze before water as temperature is lowered because it contains impurifities
Why Poes water on top of a mountain boil at a lower temperature than at sea level?
It is the effect of air pressure. The air pressure at the top of a mountain is less than the air pressure at sea level. The effect of air pressure on a water surface is to prevent or oppose water molecules escaping from the surface. The greater the air pressure, the more heat energy is needed to allow the water molecules to escape and so at sea level the water will boil at a higher temperature than if it were on top of a mountain.
