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.
Why is food cooked quickly 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.
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.
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.
Why the boiling point of water in pressure cooker high?
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.
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.
What would be the boiling point of in a pressure cooker of water at 1.3 ATM?
190 degress
What is the principle involved in pressure cooker?
The principle involved in a pressure cooker is that increasing the pressure inside the cooker raises the boiling point of water, allowing food to cook at higher temperatures and reducing cooking time. This results in faster cooking and tenderizing of tough cuts of meat.
Does a pressure cooker raise the boiling point?
Yes, a pressure cooker raises the boiling point of water by increasing the internal pressure. This allows food to cook faster and at higher temperatures, which can help to tenderize tough cuts of meat and reduce cooking times.
In a pressure cooker a lid is screwed tightly onto a pot so that the air pressure in the t is increased. What effect if any will this have on the boiling point of water in the pot?
In a pressure cooker, the lid creates a sealed environment that prevents steam from escaping, which increases the internal pressure. This elevated pressure raises the boiling point of water above the normal 100°C (212°F). As a result, water can reach higher temperatures without boiling, allowing food to cook faster. Thus, cooking in a pressure cooker is more efficient due to this increased boiling point.
How pressure cooker follows ideal gas equation?
we know that if the external pressure increases so the boiling point increases too therefore pressure cookers are used at higher altitudes where there are generally low external pressure so pressure cookers provide artificial pressure and food can be cooked earlier
Food in a pressure cooker is cooked faster because of the?
The higher pressure raises the boiling point of water.
