Shaking two immiscible liquids increases_________________?
Correct answer: C. Area of contact
- A. Length of contact
- B. Volume of contact
- C. Area of contact
- D. all of above
Explanation
Shaking two immiscible liquids breaks one liquid into smaller droplets, increasing the total area of contact between the two phases. This improves mass transfer during processes such as solvent extraction. Students may choose d because the liquids appear to occupy more space temporarily, but shaking does not increase their total volume.

About Properties of Liquids
Liquid behavior depends on intermolecular forces, which produce surface tension, viscosity, capillary action and a definite volume without a fixed shape. The topic also covers vapor pressure, evaporation, boiling point and the effect of temperature and external pressure, while distinguishing evaporation at the surface from boiling throughout the liquid.
