The atmospheric pressure inside the pot is boosted by the trapped steam. This causes the boiling point of the water to increase from the regular 212 degrees Fahrenheit to 250 degrees Fahrenheit. This elevated temperature is the reason foods cook faster in a pressure cooker.
Why pressure cooking is faster?
At that pressure, water boils at 121°C (250°F). That means food can cook at a much higher temperature than it ever could at atmospheric pressure—and since cooking reactions speed up at higher temperatures, your food cooks faster. It also doesn’t dry out, since the water stays in liquid form.
How much faster is pressure cooking?
A pressure cooker cooks food about 30 percent faster than conventional methods like steaming, boiling, and braising. According to the American Council for an Energy-Efficient Economy, pressure cookers also use 50 to 75 percent less energy due to shorter cooking times.

How does a pressure cooker work physics?
A pressure cooker is a sealed chamber that traps the steam generated as its contents are heated. As steam builds, pressure increases, driving the boiling point of water past 212°F. In general, this higher temperature shortens cooking times and, due to a lack of evaporation, extracts flavor more efficiently from foods.
