Correct Answer

Explanation

pressure increases, which raises the boiling point of water. This higher boiling point allows food to cook faster and more efficiently. Additionally, the sealed environment of the pressure cooker prevents heat and steam from escaping, resulting in less energy wasted during the cooking process. Overall, using a pressure cooker can significantly reduce cooking time and save fuel compared to traditional cooking methods.
