    There is some liquid in a closed bottle. The amount of liquid is continuously decreasing. The vapour in the remaining part
    (a) must be saturated
    (b) must be unsaturated
    (c) may be saturated
    (d) there will be no vapour.
    digAnsr:   b
    Ans : As the liquid is decreasing, the liquid is vapourised. We know that vapourisation cannot occur in saturated air and there cannot be any liquid with no vapour at all. So, the vapour in the remaining part is unsaturated.
    Thus,
    (b) is the correct answer.
