open system
The pressure inside will be the same as what the atmospheric pressure was when the lid was closed as long as no heat is added or removed.
it is a closed system, pressure builds from heat causing trapped steam, thus food cooks faster.
Yes, negative pressure can exist in a closed system when the pressure inside the system is lower than the pressure outside.
Yes, it is possible for there to be negative pressure in a closed system.
Yes, you can pressure can food in a pressure cooker.
Pressure in a closed system is calculated by dividing the force applied on the system by the area over which the force is distributed. This formula is known as pressure force/area.

The best pressure cooker, in my opinion, is the All American 921 21-1/2-Quart Pressure Cooker.
To can using a pressure cooker effectively, follow these steps: Prepare your jars and lids by washing them thoroughly. Fill the jars with the food you want to can, leaving the appropriate amount of headspace. Place the jars in the pressure cooker, following the manufacturer's instructions for stacking and spacing. Add water to the pressure cooker according to the manufacturer's guidelines. Close and lock the lid of the pressure cooker, ensuring the pressure release valve is closed. Turn on the heat and bring the pressure cooker to the recommended pressure for canning. Process the jars for the specified amount of time, adjusting the heat as needed to maintain the pressure. Once the processing time is complete, turn off the heat and allow the pressure to naturally release. Carefully remove the jars from the pressure cooker and let them cool before storing them in a cool, dark place.
The main difference between a pressure cooker with a 15 bar and a pressure cooker with a 20 bar rating is the maximum pressure they can reach. A 20 bar pressure cooker can reach higher pressure levels than a 15 bar pressure cooker, which can affect cooking times and the tenderness of food.
To calculate water pressure in a closed system, you can use the formula: Pressure Force/Area. This means that pressure is equal to the force exerted on the water divided by the area over which the force is applied. By knowing the force and the area, you can calculate the water pressure in the closed system.
No, a rice cooker is not the same as a pressure cooker. While both appliances are used for cooking food, a rice cooker is specifically designed for cooking rice, while a pressure cooker can be used for a variety of foods and uses pressure to cook food quickly.
