Depends on the set pressure.
At 117°C, the vapor pressure of water is approximately 2566 Pa.

In a rice cooker, the gas law is applied through the control of pressure inside the cooker. When the water in the cooker reaches its boiling point, the pressure inside the cooker increases, allowing the rice to cook faster and more evenly. By adjusting the pressure and temperature, rice cookers can efficiently cook rice while preserving its texture and flavor.
The atmospheric pressure inside a pressure cooker can reach around 15 psi (pounds per square inch) above normal atmospheric pressure. This higher pressure increases the boiling point of water and allows for faster cooking times.
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.
To prevent accidents due to high pressure inside a pressure cooker, it is important to follow these safety measures: Always ensure the pressure cooker is properly sealed before cooking. Use the correct amount of liquid to create steam and maintain pressure. Never overfill the pressure cooker. Follow the manufacturer's instructions for cooking times and pressure settings. Release pressure slowly and carefully before opening the cooker. Regularly inspect the pressure release valve and gasket for any damage or wear. Keep children and pets away from the pressure cooker while it is in use. Do not attempt to force open a pressure cooker that is still pressurized.
Above 100 deg C The extent to which the temperature is higher than 100 deg C depends on the pressure inside the cooker and that is controlled by the weights on the cooker valve.
we know that if the external pressure increases so the boiling point increases too therefore pressure cookers are used at higher altitudes where there are generally low external pressure so pressure cookers provide artificial pressure and food can be cooked earlier
Yes, you can pressure can food in a pressure cooker.
To cook frozen meatballs in a pressure cooker, add a cup of water to the cooker, place the frozen meatballs inside, and cook on high pressure for 5-7 minutes. Release the pressure naturally for 5 minutes, then quick release any remaining pressure. Enjoy your cooked meatballs!
Vapour rom the boiling water is not allowed to escape and so the pressure above the water increases. This raises the temperature at which the water inside the cooker boils.
The highest temperature reached inside a pressure cooker will depend on the pressure level set for cooking. As pressure builds up, the boiling point of water increases, allowing food to cook at higher temperatures than under normal atmospheric conditions.
