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

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.
Because the boiling point of water increases as the pressure increases, the pressure built up inside the cooker allows the liquid in the pot to rise to a higher temperature before boiling thus cooking the food faster than usual.
Jams and jellies can be canned without a pressure cooker or canner. They simply need to be cooked and poured into hot, sterilized canning jars.
Kentucky Fried Chicken is cooked in an oil based pressure cooker.
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.
In pressure cooker temperature rises to about 120 degree centigrade due to higher pressure than atmospheric pressure. Witch makes it makes food to get cooked faster than in open pot where water boils at 100 degree centigrade. Pressure cooker becomes essential at high altitude where water may boil at about 70 degree centigrade.
