1. What is the cooking efficiency metric?Reduces cooking time by 50-75% compared to conventional boiling methods
2. What is a pressure cooker and how does it cook food faster?A pressure cooker is a sealed pot that traps steam. The trapped steam raises the pressure and temperature inside, so food cooks in about a quarter to a half of the time it would take on the stove.
3. Why does the pressure cooker make food taste better?The high heat and pressure help the Maillard reaction and caramelization happen more quickly, giving foods richer flavors.

Clausius-Clapeyron Relation: A thermodynamic equation that describes the relationship between pressure and temperature for a phase transition.
Denaturation: The process where proteins lose their normal three-dimensional structure due to heat or other factors.
Ambient Atmospheric Pressure: The standard pressure exerted by the Earth's atmosphere at sea level.
