Question

In a pressure cooker, the cooking is faster because _________.

• A. more steam is available to cook the food at ${1000}^{\circ }C$
• B. the boiling point of water is lowered by the increased pressure
• C. the boiling point of water is raised by the increased pressure inside the cooker
• D. None of the above

Answer 1

The correct option is C the boiling point of water is raised by the increased pressure inside the cooker

Boiling point of a liquid increases with increase in external pressure.

In pressure cooker, pressure is higher compared to the atmospheric pressure at sea level, so boiling point of water increases.

Higher boiling point of water, allows to cook food at higher temperatures without burning it.
