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?
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.
