Chemistry Question on Colligative Properties
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 in pressure cooker
Answer
B.P. increase with increasing pressure
Explanation
Solution
The beans are cooked earlier in a pressure cooker because the boiling point increases 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 increases which leads to faster cooking.
