Question:
Shweta mixed two liquids A and B of 10 mL each. After mixing, the volume of the solution was found to be 20.2 mL.
(i) Why was there a volume change after mixing the liquids?
(ii) Will there be an increase or decrease of temperature after mixing?
(iii) Give one example for this type of solution.

Show Hint
Consider both volume and heat changes when mixing liquids. Some solutions exhibit non-ideal behavior, leading to volume contractions or expansions.

Solution and Explanation
The volume change occurs because the volume of the solution may either expand or contract
due to the interactions between molecules. This could happen due to the formation of a non
ideal solution.
