Pressure Cookers raise the boiling point of water. As pressure increases on a liquid, so does the boiling point. This is due to the fact that a liquid will not boil until the vapor pressure of the liquid is equals the environmental pressure surrounding the liquid. Think of it essentially as the surrounding pressure holds the substance in liquid form until it has enough energy to escape into gas form.

What 2 factors affect the boiling point of water?
Pressure & Temperature :) Apex
Why boiling point of water is not fixed?
The boiling point of water is fixed but boiling points depends on the atmospheric pressure.
When will water boil over 100 degrees celsius?
If the ambient pressure is increased, then the boiling point temperature will rise. This is how pressure cookers operate. There are many phase diagrams for water available online. Unfortunately, link posting is not available in wikianswers at this time.
What is the effect of decreased pressure on the boiling and freezing point?
As pressure decreases, the boiling point of water will also decrease. Backpackers camping in the high mountains are familiar with the phenomena when they get water boiling - and find that it is still only lukewarm because the atmospheric pressure at their high altitude is so low.
What does an increase in pressure on the surface of water do to the boiling point?
It will raise the boiling point. This why, for example, car radiators have a pressure cap. This causes a rise in the boiling point of the water and it is less likely to boil.
Why doesn't water get hotter than 110 degrees?
could be that this is the boiling point? so can't get hotter unless controlled in a sealed container ie steam ========== The boiling point of water is dependent on the surrounding pressure. At sea level, the expected pressure is about 1 atm and the boiling point is 100 °C. As you go up in altitude, it drops. At an elevation of around 2500 m it has dropped to a point that the water is kind of luke-warm when it boils. If you add salt or something to the water, you can elevate the boiling point a bit - even getting it up to 110 °C, but if you want to get it higher you have to keep it under pressure. That's the point of pressure cookers and pressure canning vessels. Some doctors use hydroclaves to sterilize instruments - essentially they are just pressure cookers for medical instruments.

What is the boilinge point of water?
The boiling point of water depends on the pressure. At 1 atmosphere pressure, the boiling point is 100ºC or 212ºF.
Why boiling point of water is not fixed?
The boiling point of water is fixed but boiling points depends on the atmospheric pressure.
what are the changes in the boiling point of water in high air pressure?
The boiling point increase at high pressure.
What factor besides the temperature affects the boiling point of water?
Air pressure also affects the boiling point of water. The higher the air pressure, the higher the boiling point.
What happends to water's boiling point as pressure is increased?
boiling point increases
When will water boil over 100 degrees celsius?
If the ambient pressure is increased, then the boiling point temperature will rise. This is how pressure cookers operate. There are many phase diagrams for water available online. Unfortunately, link posting is not available in wikianswers at this time.
When boiler pressure increases what happens to the boiling point of water?
The boiling point of water is dependent on environmental factors and the presence of solutes. In this case the pressure of the system on the water serves to increase the boiling point of water. The higher pressures increase boiling points while lowering pressure decreases it.
What is the effect of decreased pressure on the boiling and freezing point?
As pressure decreases, the boiling point of water will also decrease. Backpackers camping in the high mountains are familiar with the phenomena when they get water boiling - and find that it is still only lukewarm because the atmospheric pressure at their high altitude is so low.
What does an increase in pressure on the surface of water do to the boiling point?
It will raise the boiling point. This why, for example, car radiators have a pressure cap. This causes a rise in the boiling point of the water and it is less likely to boil.
How does pressure change the boiling point of gasoline?
Higher pressure increase the boiling point of gasoline, just like with water.
