Answer

(i) Ravi will cook the vegetables faster. Pressure cookers heat food quickly because the internal steam pressure from boiling liquid causes the wet steam to permeate food.

This transfers more heat rapidly.

(ii) At high altitudes the atmospheric pressure is low. This reduces the boiling point of water and thus, cooking is delayed.

(iii) Presence of mind and scientific thinking.
