Boiling point = temperature where the vapour pressure is equal to the pressure of the atmosphere above the liquid.
When you have a pressure cooker, the pressure above the water is higher than atmospheric pressure, therefore the boiling point of water is elevated to above the boiling point in an open pot. The water temperature exceeds 100 degrees Celsius, and thus the cooking process is accelerated.

How does a pressure cooker work to cook food quickly and efficiently?
A pressure cooker works by trapping steam inside a sealed pot, which increases the pressure and temperature. This allows food to cook faster and more efficiently compared to traditional cooking methods. The high pressure forces moisture into the food, resulting in faster cooking times and tenderizing tough cuts of meat.
How does a pressure switch work in a circuit?
A pressure switch works by responding to changes in pressure levels. When the pressure reaches a preset point, the switch triggers a change in the electrical circuit, either turning on or off a connected device. It does this by physically opening or closing internal contacts within the switch.
How does a mercury pressure device work?
A mercury pressure device, such as a manometer, works based on the principle that the pressure of a fluid is directly proportional to the height of the fluid column. In a mercury manometer, a column of mercury is used to measure the pressure difference between two points. The difference in height of the mercury column indicates the pressure difference between the two points.
How does the hydroskeleton work?
A hydroskeleton works by using fluid-filled cavities surrounded by muscles to create support and movement. When the muscles contract, they apply pressure to the fluid, causing the structure to stiffen and move, providing support for the organism. This system is commonly seen in invertebrates like jellyfish and earthworms.
How an airspeed indicator works?
An airspeed indicator works by measuring the difference between the ram air pressure from the pitot tube (which faces forward into the airstream) and the static air pressure from the static port. The difference in pressures is converted into an airspeed reading on the instrument display. As the aircraft moves through the air, the pressure differential changes, and the airspeed indicator reflects these changes in real time.
Is there a relationship between boiling and pressure?
Yes, there is. Higher pressure increases the boiling point and lower pressure decreases it. That is why a pressure cooker works and why water boils at lower temperatures in high altitudes.
Are pressure cooker dangerous?
The main danger in using a modern pressure cooker is being burned by steam.Modern pressure cookers have been re-engineered to eliminate the kitchen explosions of the past. They now have a number of safety features built in that prevent and release over pressure. But by the very nature of how a pressure cooker works there is still a slight chance of a steam burn occuring. Read the instruction manual and follow it and you shouldn't have any problems.

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.
What food cooks the fastest using a solar cooker?
A parabola solar cooker works the best and fastest
How does pressure affect the steaming process?
A pressure cooker speeds up cooking time. It works by holding some of the steam inside. This raises the temperature and forces the steam into the food so everything cooks faster.
What gas law could apply to how refrigerator works?
convection currents
Where can you download instructions for tower 4300 pressure cooker?
I have a 4-quart SKY-LINE pressure cooker purchased in a mountaineering store in (probably) the early 1960. And yes, it still works very well. Unfortunately the rubber gasket that held the fusible plug has gone to the great kitchen in the sky. I have temporarily sealed the 5/8" hole with a rubber stopper, but that leaves only the pop-off valve to prevent over-pressurization. Can any one help me? John Geobuff@hotmail.com

it doesnt it just eats big toes
What happens to the boiling point when pressure increases in cooker?
It's higher-this is how a radiator works in a car. Since system pressurized boiling point above 212. Some cars fans don't even come on until they hit 220.
Why is cooking time reduced when using a pressure cooker?
A pressure cooker doesn't allow for anything (even gases) to escape at any significant amounts (unless the pressure inside gets too high and you hear that whistleing noise). With heat, the gases inside want to expand, but because they are restricted to the volume of the pressure cooker they can't, so pressure builds up. In addition, when a liquid, lets say water in this case, is heated under normal pressure its temperature won't go above 100C, because any water molecule that has higher energy leaves the liquid and goes into gas phase. Now, applying pressure to water, will increase the boiling point (for example from 100C to 110C) Reason: When any liquid is under higher pressure it is less likely to go in the gaseous phase. The pressure cooker works with these principles, because usually when you cook water in an open pot, the boiling point of water restricts the temperature to a 100C. A pressure cooker uses the pressure to keep the water in the liquid form even though it is far above the boiling point, and hence the temperature is far above 100C. Because the pressure build up inside causes higher cooking temperatures thus reducing cooking times.
What is a cooker?
A cooker is a device that helps you to boil foods and makes them hotter and sometimes safer (meat) to eat, also known as a Stove. A Microwave works the same way... A Cooker heats things up and makes them tastier or safer or cleaner sometimes!Lucy.
