    When a liquid A is mixed with liquid B, the resulting solution is found to be cooler. What do you conclude about the nature of the solution?
    Answer:

    The solution shows a positive deviation. Absorption of heat takes place. A-B interactions are weaker than A-A and B-B interactions.

    50 mL of a liquid A when mixed with 50 mL of liquid B, the resulting volume is 100.5 ml. What do you think about nature of solution?

    Answer:

    The solution will show a positive deviation from Raoult’s law. Increase in volume means A-B attractions are weaker than A-A and B-B attractions.

    What will happen to the value of colligative property of a solution if the weight of solute dissolved is doubled and weight of solvent taken is halved?
    Answer:

     The colligative property increase as we increase the concentration of solute.

    The value of colligative property will be four times because the concentration will become four times.
