Question
UPSC Prelims 2021 Question:
In a pressure cooker, the temperature at which the food is cooked depends mainly upon which of the following?
- Area of the hole in the lid
- Temperature of the flame
- Weight of the lid
Select the correct answer using the code given below.
Answer (Detailed Solution Below)
Option 3: 1 and 3 only
Detailed Solution
Explanation:
- In a pressure cooker, the pressure component is very important to reduce time for cooking. Since, Pressure = Force (weight)/Area. In a pressure cooker, the area of the hole in the lid and weight of the lid are important to determine the inside pressure which ultimately determines the cooking time. So, points 1 and 3 are correct.
- Boiling point of the cooker (Temperature inside the cooker) is also increased by pressure inside the cooker. Thus, the temperature required for cooked food is dependent on the pressure of the cooker, not on the temperature of the flame. So, point 2 is not correct.
Therefore, option (3) is the correct answer.
