Question

The Beans are cooked earlier in pressure cooker, because : -

• A. B.P. increase with increasing pressure
• B. B.P. decrease with increasing pressure
• C. Extra pressure of pressure cooker, softens the beans
• D. Internal energy is not lost while cooking is pressure cooker

Answer 1

The correct option is B B.P. decrease with increasing pressure

The beans are cooked earlier in a pressure cooker because the boiling point decreases with increasing pressure. As the pressure increases the particles come closer and due to their Kinetic energy and temperature inside the container increases and thus the boiling point decreases which lead to faster cooking.
