Q68.
In a pressure cooker, the temperature at which the food is cooked depends mainly upon which of the following? 1. Area of the hole in the lid 2. Temperature of the flame 3. Weight of the lid Select the correct answer using the code given below.
Answer
C
Explanation
Inside a pressure cooker the boiling point is increased by increasing the pressure. Hence cooking is faster. Therefore the temperature at which food is cooked is affected by the pressure and not temperature of the flame. This can also be understood by understanding why cooking is difficult on hills. At high altitudes, atmospheric pressure is lower, reducing the boiling point of water as compared to that at sea level.
