  • Vapour pressure of a liquid depends on

    A
    Volume of container
    B
    Amount of liquid
    C
    Surface area of container
    D
    Temperature

  • During phase transformation of vapour into liquid :-

    A
    It absorbs heat
    B
    It releases heat
    C
    Its temp. increases
    D
    Its temp. decreases

  • In non-ideal solutions, at one of the intermediate compositions, the total vapour pressure is highest and the boiling point is lowest. At this point, the composition of the liquid and vapour phase is same. So, if liquid mixture vapourises at this point and vapours are condensed, the condensate contains same composition as present in orginal liquid mixture. It means that at this point liquid behaves like a pure and is called as Azeotropic mixture. Choose the correct answer : Choose the correct statemnent

    A
    Ideal solutions connot be separated into their components by frectional distillation
    B
    For ideal solution, entghalpy of mixing is always greater than zero
    C
    Only non-ideal solution showing positive devialtion cannot be separeated out by fration distillation.
    D
    Non-ideal solution showing both positive and ngative deviation cannot be separated out by fractional distillation.
