A pressure cooker minimizes the escape of fluids or air. The build-up of air and fluid increases the pressure inside the cooker, which also increases the boiling point.
An open kettle allows the fluid and air to escape, heat is lost thus cooking time is longer.

∙ 14y agoBecause the pressure increases boiling point and in a pressure cooker the contents are at a high pressure causing the water to become more viscous than normal resulting in a higher boiling point.

∙ 6y agoA pressure cooker works by cooking food under high pressure. As the pressure is raised, the boiling point of water increases. The food is, therefore, cooked at a higher temperature than otherwise and this leads to a reduction in the time required.

∙ 11y agoA pressure cooker cooks food faster because under pressure the temperature is increased to a higher point than the 2120 boiling point of water in an open container.

How you measure boiling point in pressure cooker?
Normally you have a pressure of approx. 2 bar (2kPa) in a pressure cooker.At this pressure the boiling point of water is 120 0C (393 K) or 247 FSee the Related Questions to the left for more information about how pressure affects the boiling point of water.
What is the effect of dissolving salt in water on boiling point of water?
why do we use pressure cooker at hill stations for cooking food
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 2 factors affect the boiling point of water?
Pressure & Temperature :) Apex
What affect does ambient pressure have on the boiling point temperature of a liquid?
No, the external environment does not affect the boiling point of a liquid inside a pressure cooker. Since the liquid is sealed away from the air, it is not affected by ambient air pressure or humidity.

How does a pressure cooker demonstrate the effect of air pressure on waters boiling point?
Vapour rom the boiling water is not allowed to escape and so the pressure above the water increases. This raises the temperature at which the water inside the cooker boils.
Food in a pressure cooker is cooked faster because of the?
The higher pressure raises the boiling point of water.
What would be the boiling point of in a pressure cooker of water at 1.3 ATM?
190 degress
How can you change the boiling point of liquid?
you can adjust the pressure. for example water boils at a higher temperature in a pressure cooker.
What gas law could apply to how pressure cooker works?
Boiling point = temperature where the vapour pressure is equal to the pressure of the atmosphere above the liquid. When you have a pressure cooker, the pressure above the water is higher than atmospheric pressure, therefore the boiling point of water is elevated to above the boiling point in an open pot. The water temperature exceeds 100 degrees Celsius, and thus the cooking process is accelerated.
In a pressure cooker a lid is screwed tightly onto a pot so that the air pressure in the pot is increased What effect if any will this have on the boiling point of water in the pot?
THe boiling point will be raised
What is the effect of dissolving salt in water on boiling point of water?

Is there a relationship between boiling and pressure?
Yes, there is. Higher pressure increases the boiling point and lower pressure decreases it. That is why a pressure cooker works and why water boils at lower temperatures in high altitudes.
Why doeswater boil at a low boiling point on top of a mountain and a higher boiling point in a pressure cooker?
This is because the boiling point of any fluid increases as the pressure acting on it is increased. Atmospheric pressure on top of a mountain is lower than normal atmospheric pressure. Conversely, by not allowing steam to escape, the pressure above the water in a pressure cooker is allowed to build up to a much higher level.
Why food is cooked in pressure cooker?
An increase in pressure allows an increase in the boiling temperature of the liquid in the cooker. At 15 psi (the highest rated home kitchen pressure cooker) the boiling temperature of water is 250 degrees F.
What happens to the boiling point when pressure increases in cooker?
It's higher-this is how a radiator works in a car. Since system pressurized boiling point above 212. Some cars fans don't even come on until they hit 220.
