Question
Explain why cooking is faster in a pressure cooker.
✓

Answer

As in pressure cooker liquid is changed in to vapors and they increase pressure inside cooker as we know pressure is directly proportional to temperature thus temperature increases along with pressure thus food is cooked faster.
