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). … Pressure cooking requires much less water than conventional boiling, so food can be ready sooner.
How does a pressure cooker reduce cooking time?
When the pressure is normal the cooking items absorb less heat and so the cooking time is high. When the pressure is high the cooking items absorb more heat faster and so the time to cook the cooking items reduced. … When the pressure is normal the cooking items absorb less heat and so the cooking time is high.
How does a pressure cooker reduce cooking time as compared to open pan cooking?

Why do pressure cookers save time in the kitchen?
At lower pressures, water boils at a lower temperature. That means something simmering away is cooking below 100°C (212°F) and will take longer to cook. At high altitudes, by raising the pressure and boiling point above what happens at sea level, a pressure cooker can really boost the reactions cooking your food.
What does pressure cooking do to food?
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.
