Question

Why is it advisable to use pressure cooker at higher altitude

Answer 1

at higher altitude the atmospheric pressure is lower, since the atmospheric pressure is lower, water boils at a much lower temperature.
now if you were to cook something there since the water boils at a much lower temperature, the food would not get cooked right and it would remain raw to a certain extent. pressure cooker eliminates this and thus it's advisable to use a pressure cooker at higher altitude so the food gets cooked right

Answer 2

It is advisable to use pressure cookers in high altitudes because . While using pressure cookers you are in creasing the atmosphere pressure and that leads to increasing the boiling point .
