  1. Question 1

    Q1. A small weight is put on the pressure cooker; it increases the pressure of the steam because:

    • A) The weight is proportionate to the steam required
    • B) The area of contact is small
    • C) The weight stops the steam from escaping
    • D) Of Bernoulli's principle

    Answer: The area of contact is small

    Explanation: Pressure = Force ÷ Area; the small weight placed on the narrow pressure-cooker vent has a very small contact area, generating high pressure (P = F/A) that keeps steam contained.
