प्रश्न
Water boils at 120°C in a pressure cooker. Explain the reason.
लघु उत्तरीय
उत्तर
A liquid's boiling point rises as its pressure rises. By preventing steam from escaping, a pressure cooker raises the internal temperature of a liquid (water) to 120°C and the surrounding pressure to roughly 1.75 times that of the atmosphere.
