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.

How does a pressure cooker work to cook food faster?
Because the temperatures are high in pressure cooker
Why a pressure cooker is used for cooking food?
A pressure cooker will cook food faster and also tenderize tougher meats.
How food is cooked easily in pressure cooker?
During heating the pressure increase in the pressure cooker; as a consequence the temperature increase, the cooking is faster, part of energy saved, etc.
Food in a pressure cooker is cooked faster because of the?
The higher pressure raises the boiling point of water.
Why are pressure cooker used in cookery?
cooking food faster than conventional cooking
Is pressure cooker an example of the application of Charles' law?
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....
Why is a frying pan and a casserole dish better for a pressure cooker?
boiling water will cook it evenly but if you put it straight on with pressured heat it will cook faster. why? heat when pressured becomes extremely hot causing things to cook faster. As the pressure rises, the temperature of the water and steam inside the sealed pot (the pressure cooker) also rises above the normal 100ºC (212ºF) boiling point temperature.
Is it the boiling of water or the higher temperature of water that cooks food faster in a pressure cooker?
On the food
How a pressure cooker can save in cooking food and tenderizing meat faster?
it is a closed system, pressure builds from heat causing trapped steam, thus food cooks faster.
How is a pressure cooker use in saving energy for cooking and tenderizing meat faster?
pressure cookers cook faster. Instead of cooking something for 3-4 hours you can cut that down to maybe 1 hour. It tenderizes meat by forcing the steam into the food and breaking up some of the molecules
Why is it easier to cook in a pressure cooker?
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.
What is the advantage of a pressure cooker in the term of physics?
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.
