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.

The higher pressure raises the boiling point of water.
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.
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.
Yes, it is true.
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 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.
During heating the pressure increase in the pressure cooker; as a consequence the temperature increase, the cooking is faster, part of energy saved, etc.
There are many things that can be cooked without a stainless pressure cooker. It would be important to have one if you would like to cook quickly because steam cookers cook faster than other cookwares. They can also cook at a higher temperature than the boiling point of water.
temperature=pressure/area
Pressure Cooker Operation In pressure cooker,the food is cooked in closed condition ,where,there is pressure valve ,here you are increasing the pressure inside the vessel hence ,pressure inside the pan will be greater than atmospheric pressure,hence the boiling point is reached in less time and cooking takes place faster. Vacuum Pan Here vacuum is opened or reducing the pressure where air inside is removed and hence the product is cooked at lower temperature .More u increase the vacuum,more reduction in pressure and hence longer time to cook ,
