Question

Pressure cooker reduces cooking time because:

• A. the heat is more evenly distributed inside the cooker
• B. whole matter is converted into steam
• C. boiling point of water is elevated
• D. a large flame is used

Answer 1

Answer: (C)

Because under pressure, the heat builds faster and maintains temperature better, so cooking time is reduced. ... The increased pressure inside the cooker increases the boiling point of water above ${100}^{0}C$ so more cooking is done before the water actually starts to boil. So ultimately food is cooked faster.
