Food is cooked more quickly in a pressure cooker because at the higher pressure (1 bar/15 psi), the boiling point of water rises from 100 °C (212 °F) to 121 °C (250 °F). The hotter steam is able to transmit its thermal energy to the food at around 4 times the rate of conventional boiling.
Why cooking is faster in pressure cooker than in cooking pan?
Answer. this is because the pressure inside the cooker is more than the atmospheric pressure due to this the boling temp of water is also increase as compare to the b.p temp 100c in an open pot. The water vapor also transfer the heat to food particle thus increasing the speed.
Why does the food cook faster in a pressure cooker?
“And the pressure cooker traps that hot air and moisture with the food, which expedites the cooking process. “In other words, the moisture surrounding the food itself reaches higher temperatures than it would without the pressure, which speeds up the chemical processes involved in cooking.
How does a pressure cooker reduce cooking time?
As elevation increases, atmospheric pressure decreases, causing water to boil at lower temperatures, which lengthens cooking times. But a pressure cooker provides constant, precise atmospheric conditions inside the cooker, reducing cooking times even at high altitudes.

Why cooking is difficult at high altitude?
At higher altitudes, say like mountains, cooking food is difficult. Higher altitudes means lower atmospheric pressure and thus lower boiling point. … So, at higher altitude, food needs to be cooked for a longer time due to the lower in boiling point of water.
