What is the approximate pressure inside a cooker if water boiling at temperature?

The pressure inside a pressure cooker when water is boiling depends on the specific pressure cooker and the design of its pressure release valve. However, a typical pressure cooker operates at around 15 psi (1 atmosphere) above normal atmospheric pressure.

Here's why:

* Boiling Point and Pressure: The boiling point of water increases with increasing pressure. At sea level, water boils at 100°C (212°F). In a pressure cooker, the increased pressure raises the boiling point to around 121°C (249°F).

* Pressure Release Valve: The pressure release valve is designed to maintain a specific pressure inside the cooker. It releases steam when the pressure exceeds the set limit, preventing the cooker from exploding.

Important Notes:

* Specific Pressure: Different pressure cookers may have different pressure settings, typically ranging from 5-15 psi above atmospheric pressure. Check the manual for your specific cooker.

* Safety: Never exceed the maximum pressure rating of your pressure cooker. Always follow the manufacturer's instructions for safe operation.
