What is the principle involved in pressure cooker?
At higher pressures, water boils at a higher temperature. A pressure cooker lets you cook at a higher pressure than regular saucepans so you can have a higher boiling 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 can you change the boiling point of liquid?
you can adjust the pressure. for example water boils at a higher temperature in a pressure cooker.
How does pressure effects the time period of cooking food?
If you are referring to cooking with a pressure cooker, the higher pressure attained in this type of cooker allows the water to reach a higher temperature before boiling. This will cook food more quickly due to the higher temperature, which in turn is due to the higher pressure. Keep in mind that once water reaches the boiling point, the temperature remains constant; the only way to attain a higher temperature, then, is to increase the pressure.
Why the boiling point of water in pressure cooker high?
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.
Why food is cooked more rapidly in pressure cooker in covered pots?
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.
At what degrees the water boils in a pressure cooker?
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.
The temperature inside a pressure cooker is 117 C Calculate the vapor pressure of water inside the pressure cooker?
2.90
In a pressure cooker water boils at a temperature?
Yes it does.
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.
Why food is cooked in pressure cooker?
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.
Why food is cooked more quickly in pressure cooker then in a covered pot?
The greater the pressure the water is under the greater the heat required to bring it to boiling point.
