Why the food is cooked faster in the pressure cooker? Why it becomes difficult to cook food at the mountains?

Answer:

                The pressure inside the pressure cooker is very high. This raises the boiling point of water and the temperature inside the cooker is higher than \[\text{1}00{}^\circ \text{C}\] which results in faster cooking of food. At the mountains, the pressure is less, so the boiling point of water is less than \[\text{1}00{}^\circ \text{C}\]. This makes the cooking of food difficult.
