Question

The beans are cooked earlier in pressure cooker because:

• B. boiling point decreases with increasing pressure
• C. extra pressure of pressure cooker softens the beans
• D. internal energy is not lost while cooking in pressure cooker

The correct option is A boiling point increases with increasing pressure

The beans are cooked earlier in a pressure cooker because the boiling point increases with increasing pressure. That means food can cook at much higher temperature and since cooking reaction speeds up at higher temperatures, food cooks faster.
