Question

Food gets cooked quickly in a pressure cooker because of:

  1. At high pressure water gets boiled at low temperature
  2. At high pressure water gets boiled at high temperature
  3. Water boils only at 100°C but the amount of heat is high of high pressure
  4. Convection currents are generated inside the cooker

Answer:

Option B: At high pressure water gets boiled at high temperature

Detailed Solution:

The correct answer is “At high pressure water gets boiled at high temperature”.

In a pressure cooker, the pressure inside the cooker increases, which raises the boiling point of water above the normal 100°C. This higher boiling point allows the food to cook at a higher temperature, which speeds up the cooking process.
