Question

    With the increase of pressure, the boiling point of any

    substance –
    A Increases Correct Answer Incorrect Answer
    B Decreases Correct Answer Incorrect Answer
    C Remains Same Correct Answer Incorrect Answer
    D Becomes zero Correct Answer Incorrect Answer

    Solution

    The temperature stays the same until all the liquid has vaporized. As the temperature of a liquid rises, the pressure of escaping vapor also rises, and at the boiling point the pressure of the escaping vapor is equal to that exerted on the liquid by the surrounding air, causing bubbles to form.
