When a liquid drop splits into number of small drops in isolated system 

a) Volume increases 

b) Surface area increases 

c) Temperature increases 

d) Temperature decreases 

When a drop of liquid is split into a large number of drops, the surface area of the liquid increases. In this process, the molecules from the interior of the liquid rise to the surface of the drops, doing work against the cohesive force. This results in a decrease in the internal energy because energy is absorbed. Consequently, the temperature of the drop falls.
