Cookers, such as pressure cookers, are designed to create a sealed environment to build pressure while cooking, but they are not completely airtight. They have safety valves and release mechanisms to prevent excessive pressure buildup. While they minimize the escape of steam and air during cooking, some small amounts may still escape. Regular cookers, like conventional pots, are not designed to be airtight at all.
