Current Question (ID: 8143)

Question:

$\text{The beans are cooked in pressure cooker, because -}$

Options:

1. $\text{Boiling point increases with increasing pressure}$
2. $\text{Boiling point decreases with increasing pressure}$
3. $\text{Extra pressure of pressure cooker softens the beans}$
4. $\text{Internal energy is not lost while cooking in pressure cooker}$

Solution:

$\text{Explanation:}$ $\text{In a pressure cooker, the increased pressure raises the boiling point of water above } 100°\text{C (212°F). This higher temperature allows food to cook faster and more efficiently.}$ $\text{According to the Clausius-Clapeyron equation, the boiling point of a liquid is directly related to the external pressure. As pressure increases, the boiling point increases.}$ $\text{At higher temperatures, the cooking process becomes more efficient as chemical reactions proceed faster, proteins denature more quickly, and tough fibers in foods like beans break down more effectively.}$ $\text{Therefore, the correct answer is that boiling point increases with increasing pressure.}$
