Two dishes, X and Y, filled with equal amount of liquids were kept under the sun. After some time, it was observed that amount of liquid remaining in X was higher than the amount of liquid left in Y. Out of X and Y, which liquid has higher intermolecular forces of attraction?
Answers
Answer:
If after sometime it was observed that the amount of liquid left in Y is less than that of liquid x...then it can be said that some amount of liquid Y had been evaporated in presense of sunlight .That means the intermolecular bonds present there in are weak in nature and easily can be broken in presence of sunlight(heat)(hv).But ,incase of liquid x ,the bonds are strong i.e they have strong intermolecular forces of attraction and thus cannot be easily broken.Explanation:
The liquid X has higher intermolecular forces of attraction.
- As it is mentioned that the liquid remaining in X is higher than the liquid in Y.
- It means that more amount of liquid Y has evaporated and less amount of X is evaporated.
- This shows that liquid X is less volatile and liquid Y is more volatile.
- Less volatile liquid X means that it has strong intermolecular forces of attraction.
- More volatile liquid Y means it has weak intermolecular forces of attraction.
