Pressure Cooker – Working Function A pressure cooker works on the principle of high pressure increasing the boiling point of water. This helps food cook faster. 1. Sealed Container The cooker is tightly sealed with a lid so steam cannot escape easily. 2. Heating Water When the cooker is heated, the water inside turns into steam. 3. Increase in Pressure Since the steam cannot escape, the pressure inside the cooker increases. 4. Higher Boiling Point Due to high pressure, the boiling point of water rises from 100 °C to about 120 °C. 5. Faster Cooking At this higher temperature, food cooks much faster and more evenly. 6. Safety Valve The pressure valve (whistle) releases extra steam to prevent the cooker from exploding.
