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.

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.
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 do vegetables cook better and faster in a pressure cooker?
Because the boiling point of water increases as the pressure increases, the pressure built up inside the cooker allows the liquid in the pot to rise to a higher temperature before boiling thus cooking the food faster than usual.
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.
Does a pressure cooker raise the boiling point?
Yes, it is true.
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
What are Pressure cooker. it is boiler or not?
no, it is not a boiler. pressure cookers are pots that use pressure to cook food. now where there is pressure, there is heat. It's simple science. The heat then cooks the food. happy cooking!!added answer: pressure does not cause heat. Pressure simply allows the boiling point of the liquid to be higher since boiling point increases with the increase of pressure. A higher boiling point causes faster cooking.
Food in a pressure cooker is cooked faster because of the?
The higher pressure raises the boiling point of water.
How is a pressure cooker use in saving energy for cooking and tenderizing meat faster?
pressure cookers cook faster. Instead of cooking something for 3-4 hours you can cut that down to maybe 1 hour. It tenderizes meat by forcing the steam into the food and breaking up some of the molecules
