A very good question! At sea-level, water boils at 100 degrees Celsius. If you increase the pressure, however, the amount of heat to boil water increases, simply because there is more air pressue holding the water vapor in solution. Water may not boil until 110 degrees in a chasm. Similarly, as you decrease the pressue, like when climbing a mountain, it will take less heat to boil water. So, water may boil at 90 degrees atop a mountain. This means, that the water will boil more quickly at lower pressures. While this may seem beneficial at first, consider that boiling water, regardless of how fast or slow it is boiling, is always at the same temperature. If you're braising something, for instance, that piece of food will spend its entire cooking time in 90 degree water, rather than 100 degree water.

Why do foods require longer microwave cooking time at higher atitudes?
The boiling point of water goes down at higher altitudes, and so foods take longer to cook (because the temperature of the food doesn't usually exceed the boiling point of water).See the Related Questions about how elevation effects the boiling point of water.
Why does it take longer to boil water at higher altitudes than lower altitudes?
Water boils at a lower temperature at higher altitudes due to decreased atmospheric pressure. This means that the water must absorb more heat energy to reach its boiling point, resulting in a longer boiling time compared to lower altitudes where boiling occurs at a higher temperature.
Where does faster to boil water at the higher place or lower place?
At higher places as the pressure is less and the water molecules can leave to the air easily
How does amount affect the rate of cooking?
Generally the higher the amount then the longer it will take to cook.
Why does it take longer to hard boil an egg at high altitudes?
At higher altitudes, the air pressure is lower, which means that water boils at a lower temperature. This lower boiling point means that it takes longer to cook the egg and harden the egg white.
Why do hard boiled eggs take longer to cook in different parts of the world?
Because altitude (how far above sea level you are) partly determines cooking time. Different parts of the world have a wide range of altitudes. At sea level, water boils at 100 degrees Celsius. At higher altitudes (lower pressures) it boils at a lower temperature.
Why does pasta take longer in the mountains?
Pasta takes longer to cook in the mountains primarily due to lower atmospheric pressure at higher altitudes, which decreases the boiling point of water. As a result, water boils at a temperature lower than the standard 100°C (212°F), leading to longer cooking times for pasta. Additionally, the reduced oxygen levels can affect the cooking process, further extending the time needed to achieve the desired texture.
Why would it take longer to boil an egg above sea level?
It takes longer to boil an egg above sea level because the atmospheric pressure decreases at higher altitudes, leading to lower boiling points. This means that the water will boil at a lower temperature, causing it to take longer to cook the egg.
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.
What are the challenges of boiling water at high altitudes?
At high altitudes, water boils at a lower temperature due to decreased air pressure. This can affect cooking times and the taste of food. Additionally, it may take longer to cook food properly, and some recipes may need adjustments to account for the lower boiling point of water.
Why cooking is difficult in high altitudes?
At higher altitudes, the atmospheric pressure becomes less because of less amount of air is present over that region and hence less weight and so less pressure. Boiling point of a liquid is the temperature at which the saturated vapour pressure of the liquid becomes equal to the outside atmospheric pressure. As the pressure at higher altitudes is less, the liquid starts boiling at lower temperature. Hence water would boil at a temperature less than 100 deg C. As temperature becomes less then the heat content would become less for every unit mass of water. So transferring heat to the food materials would take a longer time and hence cooking becomes difficult.
Why is cooking time longer at high altitudes?
Well, honey, at high altitudes, the air pressure is lower, which means water boils at a lower temperature. So, food takes longer to cook because it's not getting as hot as it would at sea level. Basically, you're playing by different rules up there in the mountains, so you gotta adjust your cooking time accordingly.
