Question

pressure cooker reduces the cooking time explain the principal involved​

Answer 1

A pressure cooker works on a simple principle: Steam pressure. A sealed pot, with a lot of steam inside, builds up high pressure, which helps food cook faster. ... As the pot heats up, the liquid inside forms steam, which raises the pressure in the pot.

WHEN WE GIVE HEAT TO PRESSURE COOKER THE STEAM INSIDE THAT IS STAYING INSIDE THE COOKER, UNTILL WE OPEN IT.

THE HEAT IS STAYING INSIDE THE COOKER IS PRODUCING MORE HEAT, THEREFORE THE FOOD IS COOKED QUICKLY,

THEREFORE YOU CAN SAY THAT PRESSURE COOKER REDUCES THE COOKING TIME
