Why does food cook faster in a pressure cooker?
Correct Answer: Option A
Explanation:
In an open vessel, water boils at 100°C, and extra heat merely creates steam rather than raising the temperature. A pressure cooker traps steam, increasing the internal pressure above atmospheric pressure. Increased pressure raises the boiling point of water (often to around 120°C). Cooking the food at this higher temperature significantly reduces cooking time.
