Why does it take longer for food to cook at hill stations?

The key factor is declining air pressure at higher altitudes. Falling air pressure lowers the boiling point of water by just under 1 degree Fahrenheit for each 500 feet of increased elevation. … Any food prepared with moist-heat methods, like boiling or simmering, will take longer to become fully cooked.

Why does it take longer to cook food in hill stations?

A. In the hills the atmospheric pressure is lower than in the plains and therefore water boils at a temperature lower than the 100oC causing an increase in cooking time. … Due to low atmospheric pressure on the hills, the water boils at a temperature higher than 100oCand therefore water takes longer to boil.

Why is it difficult to cook food on high mountain regions when compared to plane areas at ground level write the reasons?

Answers (1)

As the atmospheric pressure decreases with altitude, it will be lower at the top of mountain as compared to the ground level. Because of this the water will start boiling at lower temperature at the top of mountain as compared to ground level.

Why is it difficult to cook on hills?

This is because at high altitudes atmospheric pressure is low; therefore, boiling point of water decreases and so it does not provide the required heat energy for cooking.

Why does the vegetable cook with difficulty at hill stations?

The boiling point of water depends upon the pressure on its surface. … At higher altitudes, the atmospheric pressure is low and, therefore water boils below 100°C. Hence, sufficient heat is not supplied for cooking the vegetables at hill stations. This difficulty may be overcome by using a pressure cooker.

Does it take longer to cook at altitude?

As atmospheric pressure decreases, water boils at lower temperatures. … Because water boils at a lower temperature at higher elevations, foods that are prepared by boiling or simmering will cook at a lower temperature, and it will take longer to cook.

Why does it take longer to cook at higher altitudes physics?

The key factor is declining air pressure at higher altitudes. Falling air pressure lowers the boiling point of water by just under 1 degree Fahrenheit for each 500 feet of increased elevation. … Any food prepared with moist-heat methods, like boiling or simmering, will take longer to become fully cooked.

Why is it difficult to cook on mountains Class 11?

Answer Expert Verified

As the altitude is higher, the air column weight is reduced. So the pressure is reduced as compared to the sea level or below the mountains. Water has a lower boiling point at a lower temperature. The food items like rice or meat need to be cooked at high temperatures.

Why is it easy to cook in a pressure cooker?

As the pot is heated, the temperature inside increases until the water starts to boil. … At that pressure, water boils at 121°C (250°F). That means food can cook at a much higher temperature than it ever could at atmospheric pressure—and since cooking reactions speed up at higher temperatures, your food cooks faster.

Why does it take longer to cook rice in Shimla as compared to Delhi?

in the hills the atmospheric pressure is lower than that in the plains and therefore water boils at a temperature lower than 100oC causing an increase in cooking time.

Why cooking is easier in pressure cooker but difficult on hills?

Hence at higher altitudes, the atmospheric pressure will be low. Therefore the boiling point of water will be lower than 100 C (boiling point is the temperature at which the pressure of a liquid becomes equal to that of the surroundings). As a result, at higher altitude, food would be undercooked.

Why is the boiling point of water less than 100 0 C at hill stations?

At elevated altitudes, any cooking that involves boiling or steaming generally requires compensation for lower temperatures because the boiling point of water is lower at higher altitudes due to the decreased atmospheric pressure.

What is the difference between normal boiling point and standard boiling point?

When the external pressure is equal to one atmosphere pressure, the boiling point is called normal boiling point. When the external pressure is 1 bar,it is called standard boiling point.
