उत्तर
In a pressure cooker, the food is cooked faster because increased pressure raises the boiling point.
Explanation:
In a pressure cooker, food cooks faster because increased pressure raises the boiling point of water, allowing the food to cook at a higher temperature. This higher temperature accelerates the chemical reactions involved in cooking, resulting in a shorter cooking time.
