Why is it advisable to use pressure cooker at higher altitudes for cooking?

There are some simple facts that will help you understand this one. First, a general rule is that the hotter the source is, the faster heat is transferred into food, and the faster it will cook. (The trick is not to burn the food on the outside.) Second, water in an open cooking vessel cannot get hotter than its boiling point, and the boiling point of water at altitude is lower than it is at sea level. The pressure cooker allows the pressurized water to achieve a higher temperature than it otherwise could, and this makes the device more useful for high altitude cooking.

∙ 11y agoat high altitudes atmospheric pressure is low .Subsequently the liquids will boil at low temperature in comparison with that at the sea level . As water boils at low temperatures the pressure cooker is used for cooking on hills

∙ 12y agoThough the outside pressure is less at higher altitudes, in the pressure cooker the pressure will be high. The boiling point depends on the pressure. Higher the pressure, higher the boiling point. Hence cooking becomes faster and easier.

For every 1000 feet you go up the boiling point drops by 1 degrees Celsius. So at 3000 feet the boiling point is 97 degrees Celsius. This means that for every 3000 feet you climb it takes an extra 30 minutes to kook stuff in boiling water.
Thus at 18000 feet, high in the mountains, the water will only reach 82 degrees Celsius for it to boil - this is not rally hot enough to cook things properly.
A pressure cooker traps the steam in the pot and the weight on the outlet raises the pressure in the post, counteracting the drop in atmospheric pressure and allowing food to be cooked quicker again.

∙ 11y agoit is advised to use pressure cookers because it minimise the loss of energy
Wiki User
∙ 12y agobecause at mountain pressure is very very less.so we need a pressure cooker there
Wiki User
∙ 12y agoBecause the reduced air pressure at altitude means that food takes much longer to cook.

Will cooking in a pressure cooker destroy minerals in food?
No
How much do cooking times change when using a pressure cooker instead of a normal pot?
Between cooking with a normal pot and a pressure cooker the difference in terms of time is not much. The pressure cooker can be used depending on the type of food that is cooked.
Why a pressure cooker is used for cooking food?
A pressure cooker will cook food faster and also tenderize tougher meats.
Why are pressure cooker used in cookery?
cooking food faster than conventional cooking
Why is the pressure cooker a useful utensil?
The time for cooking is lower.
Why is a pressure cooker used to cook at higher altitudes?
The boiling point of a liquid goes down as the atmospheric pressure decreases. At sea level water boils at 100 degrees C. As you go up higher the air pressure decreases (because there's less air above you). In 'mile high' Denver, Colorado, water boils at about 95 degrees C. Cooking, like all chemical reactions happens more slowly as the temperature decreases. Thus anything you cook by boiling will take longer at high altitudes. In a pressure cooker the pressure is higher than it is outside, so the water boils at a higher temperature and cooking times are reduced. In fact you don't have to live at high altitudes to benefit from using a pressure cooker. Even at sea level they are useful, especially for reducing the time for slow dishes such as stews, which is convenient and saves fuel.
How food is cooked easily in pressure cooker?
During heating the pressure increase in the pressure cooker; as a consequence the temperature increase, the cooking is faster, part of energy saved, etc.
Where online can I read more about cooker pressure and find recipies for my presser cooker?
The website http://allrecipes.com//Recipes/everyday-cooking/pressure-cooker/Main.aspx has some great recipes available. They are easy to make and very simple when using the pressure cooker.
How is solar cooker different from a normal pressure cooker?
A solar cooker and a pressure cooker are two completely different ways of cooking. A pressure cooker can still use a heat source like a gas or electric cook top. A solar cooker is as the mercy of the heat of the sun and the contents will only cook as well as the amount of heat it obtains.
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.
How do I know when I've reached the right cooker pressure?
You can know when you have reached the right cooker pressure by checking the temperature gauge. The right temperature would also depend on what you are cooking.
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.
