Question

Regular cooking in vessel open to atmosphere takes long time in are mountains therefore cooking in pressure cookers is advised now the answer the following questions why does cooking in vessel open to atmosphere take long time in mountains and why does cooking in pressure cooker take less time and name any other advantages of using cooker pressure instead of cooking in open vessel

Answer 1

Regular cooking vessel open to atmosphere takes longer time because
The atmospheric pressure in mountains is less than that of a plain ground so we need to put more pressure to cook something in mountains and so pressure cooker is used.And one advantage is the something that is getting cooked is boiled better that in an open vessel.

Hope it helps you

Answer 2

Answer:

Boiling point of any liquid increases as the pressure acting over the liquid increases. At higher altitudes, atmospheric pressure is low and thus water boils at temperature lower than

100°C. As a result, the heat provided to open vessel is less, while cooking food for a given period..in a pressure cooker, the pressure is higher than one atmosphere. Due to higher pressure, water.boils at higher temperature than 100°C. Hence more heat is provided for a given time period to cook food and cooking food takes less time. Thus, fuel consumption is less while using pressure cookers to cook food. As it takes less fuel and less time, thus cooking food in pressure cooker is advantageous as compared to cooking in open vessels.
