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.
temperature=pressure/area
why food is cooked more quickly in a pressure cooker then in a covered pot show its properties chemically
The higher pressure raises the boiling point of water.
During heating the pressure increase in the pressure cooker; as a consequence the temperature increase, the cooking is faster, part of energy saved, etc.

Between cooking with a normal pot and a pressure cooker the difference in terms of time is not much. The pressure cooker can be used depending on the type of food that is cooked.
The greater the pressure the water is under the greater the heat required to bring it to boiling point.
You can cook just about any kind of food in any sort of cookware as long as you have the experience. You can google for a lot of results on what is best cooked in a pressure cooker.
A pressure cooker will cook food faster and also tenderize tougher meats.
The higher the amount of heat the faster the food is cooked. Generally speaking the temperature of water doesn't go much over 212ºF(100ºC) and at higher elevations the temperature can be less. This is because water will boil at a lower temperature if it is under less pressure. When the pressure cooker maintains the contents under pressure the water can surpass the normal boiling temperature.
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.
Because the temperatures are high in pressure cooker
