Answer Details
The working principle of a pressure cooker is based on the increase in the pressure of the pot. When a liquid is heated, its temperature increases, and it evaporates to form steam. In a normal cooking pot, the steam escapes into the atmosphere, and the pressure inside the pot remains constant. However, in a pressure cooker, the lid is airtight, which prevents the steam from escaping. As the steam is continuously generated, it builds up pressure inside the cooker, which increases the boiling point of water. This allows the food to cook faster and more evenly because the higher temperature causes the food to become tender quickly. In summary, the pressure cooker works by trapping the steam inside and increasing the pressure of the pot.
