Answer to Question #307029 in General Chemistry for Joan

Question

Why do pressure cookers save time in the kitchen? Explain the effect of pressure on boiling point

Answer 1

According the Ideal gas law pV = nRT increasing of pressure increases the temperature. The increased pressure inside the cooker increases the boiling point of water above 100°C, so more cooking is done before the water actually starts to boil. So ultimately food is cooked faster.
