Question

Beans get cooked earlier in a pressure cooker, because:

A

The boiling point increases with increasing pressure

B

The boiling point decreases with increasing pressure

C

The extra pressure of the pressure cooker softens the beans

D

Internal energy is not lost while cooking in a pressure cooker

Step-by-Step Solution

A liquid boils at the temperature at which its vapour pressure becomes equal to the external pressure . In a pressure cooker, the steam is trapped inside, which increases the pressure over the surface of the liquid water to greater than normal atmospheric pressure. Consequently, the boiling point of water increases. Because water boils at a higher temperature, it provides more thermal energy to the beans, cooking them much faster.

Exam Context & Concepts Covered

This question aligns with the NEET CHEMISTRY syllabus, specifically targeting concepts from Solutions. Mastering this topic is crucial for scoring well in the upcoming medical entrance examinations. Solving conceptually related problems will help you understand the nuances of these concepts and improve your problem-solving speed.
