WebApr 3, 2024 · Complete step by step answer: A pressure cooker is based on the principle that with the increase in pressure, boiling point of water increases. It works by capturing the steam which increases the pressure in the vessel. Due to increase in pressure the boiling point of water rises up. Pressure cookers are a convenient kitchen appliance used to cook food quickly with the power of steam pressure. Even without pressure steam conducts heat and cooks faster than dry air, but with increased pressure, the steam can rise above its usual maximum temperature and cook even faster.
