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.

Why does pasta take longer to cook in boiling water at elevations high above sea level?
The boiling point of any liquid is dependent upon the pressure of the atmosphere above the liquid therefore water boils at a lower temperature at higher altitudes. Because of this, the pasta takes longer to cook in the cooler boiling water.
How much energy do you need to cook an egg?
You need 40 Pounds or 20 KG to cook an egg because if you have 20 KG When you have 5 Kg hand power.
What is the first known inhabitants of Hawaii?
Apart from the Hawaiians, the person who 'discovered' Hawaii was Capt James Cook. There is also a 16th century Spaniard who claimed to have been there, but left no written proof, so is not credited with the discovery.
When do we use the Air hole open?
when you needed to cook something fast
Why does some food float and some food not?
Whether an object floats or not depends on its density. Density is the amount of mass in a volume, or mass divided by volume. If and object's density is less than that of water, it will float in water, and if an objects density is higher than that of water, it will sink in water. raw material (fishballs will sink down);but it will floats when it is cook. why
What is the principle involved in pressure cooker?
At higher pressures, water boils at a higher temperature. A pressure cooker lets you cook at a higher pressure than regular saucepans so you can have a higher boiling temperature
Can you pressure cook a pint jar in a pressure cooker?
Yes you can pressure cook a pint jar in a pressure cooker.
How does a pressure cooker work to cook food faster?
Because the temperatures are high in pressure cooker
Why would water in a laboratory boil at a temperature lower than 100 degrees celsius?
Not only in the laboratory, also at higher altitudes. The boiling point of water depends on the pressure. "100 degrees" is only at some pressure defined as standard pressure. At high altitudes (cities like La Paz, for example), it takes longer to cook food - because water boils at a lower temperature.Not only in the laboratory, also at higher altitudes.

Is it important to have a stainless pressure cooker?
There are many things that can be cooked without a stainless pressure cooker. It would be important to have one if you would like to cook quickly because steam cookers cook faster than other cookwares. They can also cook at a higher temperature than the boiling point of water.
Can you use pressure cooker to cook dry foods?
no
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.
Why a pressure cooker is used for cooking food?
A pressure cooker will cook food faster and also tenderize tougher meats.
Why do mountaineers carry with them pressure cooker?
because external pressure is low on the montains and food dont cook easily that is why mountainers carry with them pressure cooker........

How does pressure effects the time period of cooking food?
If you are referring to cooking with a pressure cooker, the higher pressure attained in this type of cooker allows the water to reach a higher temperature before boiling. This will cook food more quickly due to the higher temperature, which in turn is due to the higher pressure. Keep in mind that once water reaches the boiling point, the temperature remains constant; the only way to attain a higher temperature, then, is to increase the pressure.
What is the difference between a pressure cooker and a vacuum pressure cooker?
A pressure cooker uses steam from water to cook food and is usually found in a residential setting. A pressure fryer uses oil to cook the food. Pressure fryers are only found in restaurants and are generally used to fry chicken.
