Question

Maximum temperature inside pressure cooker depends on:

  1. Area of hole on die top and weight kept on it
  2. Area of hole on the top and food being cooked
  3. Weight kept on hole at top and food being cooked
  4. Area of hole on the top only

Answer:

Option A: Area of hole on die top and weight kept on it

Detailed Solution:

The correct answer is “Area of hole on die top and weight kept on it”.

Area of the hole determines the rate at which steam escapes. A smaller hole will trap more steam, increasing pressure and temperature. Weight on the top controls the pressure inside the cooker. A heavier weight increases pressure, leading to a higher boiling point of water and thus, a higher temperature.
