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.
During heating the pressure increase in the pressure cooker; as a consequence the temperature increase, the cooking is faster, part of energy saved, etc.
At 117°C, the vapor pressure of water is approximately 2566 Pa.
Yes it could. It needs to be heated under pressure and for the increase in temperature required, a pressure cooker will be more than enough.
A pressure cooker minimizes the escape of fluids or air. The build-up of air and fluid increases the pressure inside the cooker, which also increases the boiling point. An open kettle allows the fluid and air to escape, heat is lost thus cooking time is longer.
Boyle's law states that the pressure of a gas is inversely proportional to its volume at constant temperature. In a pressure cooker, as the volume decreases due to the sealed environment, the pressure inside increases, allowing the temperature to rise above the boiling point of water and cook food faster.
You can know when you have reached the right cooker pressure by checking the temperature gauge. The right temperature would also depend on what you are cooking.
An increase in pressure allows an increase in the boiling temperature of the liquid in the cooker. At 15 psi (the highest rated home kitchen pressure cooker) the boiling temperature of water is 250 degrees F.

To cook chicken tenderloin in a pressure cooker, season the tenderloins with your desired spices, add a cup of liquid (such as broth or water) to the pressure cooker, place the chicken in the cooker, and cook on high pressure for 8-10 minutes. Allow the pressure to release naturally for a few minutes before opening the cooker. Check the internal temperature of the chicken to ensure it has reached 165F before serving.

Allow the pressure to release naturally for a few minutes before opening the cooker. Check the internal temperature of the chicken to ensure it has reached 165F for safe consumption.
yes pressure cooker is an example for both charles' law and boyle's. under constant volume temperature is directly proportional to pressure, where the pressure is directly proportional to temperature. so when the stove heats the cooker it increase the in the pressure which in turn increase the internal temprature and cooks the food faster....
By heating the pressure increase and again the temperature increase.

The universal gas law states that (pressure * volume/temperature) of a gas is a constant. Hence, if the volume stays the same (as in a pressure cooker), the air in the cooker can increase in temperature beyond the boiling point of water as pressure builds up over the normal atmospheric pressure. A higher temperature means faster cooking. The above is a very simplistic view of the physics involved.
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.
