{'pressure cooker': [0, 0, 1, 2], 'temperature': [0, 1, 1, 7], 'lid': [0, 0, 0, 4], 'flame': [0, 0, 1, 3], 'weight': [0, 0, 1, 1]}
The temperature at which the food is cooked in a pressure cooker depends on all three factors: the area of the hole in the lid, the temperature of the flame, and the weight of the lid. The area of the hole in the lid determines the amount of steam that can escape, which affects the pressure inside the cooker. The temperature of the flame affects the heat input into the cooker, which in turn affects the temperature inside. The weight of the lid determines the pressure inside the cooker, which affects the boiling point of water and hence the temperature inside.
